2be8ae5898 staging: comedi: comedi_fops: absorb comedi_free_board_minor()
This function is only called by comedi_cleanup_board_minors() and the
'minor' parameter will always be < COMEDI_NUM_BOARD_MINORS.

For aesthetics, absorb the function and remove the unnecessary BUG_ON().

Split the comedi_clear_board_minor() out to clarify that the return value
is a comedi_device pointer.

Drivers should not crash the kernel.

This function is only called by comedi_device_detach_cleanup() and the
s->minor will always be valid or the device wouldn't have attached in
the first place.

Leave the checks for safety in accessing the comedi_subdevice_minor_table
array but remove the BUG_ON() calls.

6b3703f4cb staging: comedi: comedi_fops: remove BUG_ON() in comedi_cleanup()
The BUG_ON() checks in this function are not necessary.

comedi_cleanup_board_minors() clears all the entries in the
comedi_board_minor_table array and will call comedi_device_cleanup()
for all attached devices. comedi_device_cleanup() will then
clear the entries in the comedi_subdevice_minor_table array with
comedi_free_subdevice_minor().

Remove the BUG_ON(), drivers should not crash the kernel.

0bb6419ccf staging: comedi: comedi_fops: remove remaining BUG_ON() checks
The BUG_ON() checks in comedi_subdevice_from_minor() and
comedi_dev_get_from_subdevice_minor() are not necessary.

The 'minor' numbers for a given comedi driver are setup by
comedi_dev_get_from_subdevice_minor() and will always be in
the correct range.

Drivers should not crash the kernel, remove the BUG_ON() checks.

According to the (broken) original driver, data[4] passed to this function

365741e6a6 staging: comedi: ni_usb6501: fix possible out-of-bounds access
Coverity reports a possible Out-of-bounds access (ARRAY_VS_SINGLETON)
with the 'const u8 *port' parameter passed to ni6501_port_command().
This param is an actual array for the SET_PORT_DIR operation, called
by ni6501_dio_insn_config(). But for the WRITE_PORT and READ_PORT
operations, called by ni6501_dio_insn_bits(), it is just the address
of an u8 local variable.

Fix the coverity issue by changing the parameter to an unsigned int
and pass the raw values from ni6501_dio_insn_config() and
ni6501_dio_insn_bits(). ni6501_port_command() then handles the masking
and shifting needed to load the value into the u8 transmit buffer.

For consistency, change the access of the 'bitmap' parameter from an
array access to a pointer operation.

1c46ae0af6 Second set of new device support, features and cleanup for the 4.3 cycle.
Take 2 also includes a fix set that was too late for the 4.2 cycle.
 
 As we had a lot of tools and docs work in this set, I have broken those
 out into their own categories in this description.
 
 Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
 * Poll functions for both event chardev and the buffer one were returning
   negative error codes (via a positive value).
 * A recent change to lsiio adding some error handling that was wrong and
   stopped the tool working.
 * bmg160 was missing some dependencies in Kconfig
 * berlin2-adc had a misshandled register (wrote a value rather than a bitmap)
 
 New device support
 * TI opt3001 light sensor
 * TXC PA12 ALS and proximity sensor.
 * mcp3301 ADC support (in mcp320x driver)
 * ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
   common support to allow different WHOAMI register addresses, devices with
   fixed scale and allow interrupt equiped magnetometers).
 * ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
 * ADIS16266 gyro (in the adis16260 driver)
 * ADIS16137 gyro (in the adis16136 driver)
 
 New functionality
 * mmc35240 DT bindings.
 * Inverse unit conversion macros to aid handing of values written to sysfs
   attributes.
 
 Core cleanup
 * Forward declaration of struct iio_trigger to avoid a compile warning.
 
 Driver cleanup / fixes
 * mxs-lradc
   - Clarify which parts are supported.
   - Fix spelling erorrs.
   - Missing/extra includes
   - reorder includes
   - add datasheet name listings for all usable channels (to allow them
     to be bound by name from consumer drivers)
 * acpi-als - add some function prefixes as per general iio style.
 * bmc150_magn - replace a magic value with the existing define.
 * vf610 - determine possible sample frequencies taking into account the
   electrical characteristics (defining a minimum sample time)
 * dht11
   - whitespace
   - additional docs
   - avoid mulitple assignments in one line
   - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
     previously used for timing.
 * Fix all drivers that consider 0 a valid IRQ for historical reasons.
 * Export I2C module alias info where previously missing (to allow autoprobing)
 * Export OF module alias info where previously missing.
 * mmc35240 - switch some variables into arrays to improve readability.
 * mlx90614 - define some magic numbers for readability.
 * bmc150_magn
   - expand area locked by a mutex to cover all the use of the
     data->buffer.
   - use descriptive naming for a mask instead of a magic value.
 * berin2-adc
   - pass up an error code rather that a generic error
   - constify the iio_chan_spec
   - some other little tidy ups.
 * stk8312
   - fix a dependency on triggered buffers in kconfig
   - add a check for invalid attribute values
   - improve error handling by returning error codes where possible and
     return immediately where relevant
   - rework macro defs to use GENMASK etc
   - change some variable types to reduce unnecessary casting
   - clean up code style
   - drop a local buffer copy for bulk reads and use the one in data->buffer
      instead.
 * adis16400 - the adis16448 gyroscope scale was wrong.
 * adis16480 - some more wrong scales for various parts.
 * adis16300 - has an undocumented product id and serial number registers so
   use them.
 * iio_simple_dummy - fix some wrong code indentation.
 * bmc150-accel - use the chip ID to detect the chip present rather than
   verifying the expected part was there.  This was in response to a wrong
   ACPI entry on the WinBook TW100.
 * mma8452
   - fix _get_hp_filter_index
   - drop a double include
   - pass up an error code rather than rewriting it
   - range check input values to attribute writes
   - register defs tidy up using GENMASK and reordering them to be easier to
     follow.
   - various coding style cleanups
   - put the Kconfig entry in the write place (alphabetically).
 
 Tools related
 * Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
   use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
   them in the middle of normal output.
 * Fix tools to allow that scale and offset attributes are optional.
 * More tools fixes including allowing true 32bit data (previously an overflow
   prevented more than 31bits)
 * Drop a stray header guard that ended up in a c file.
 * Make calc_digits static as it isn't exported or in the header.
 * Set ci_array pointer to NULL after free as a protection against non safe
   usage of the tools core code.  Also convert a double pointer to a single
   one as the extra level of indirection was unnecessary.
 
 Docs
 * DocBook introduction by Daniel Baluta.  Glad we are beginning to
   draw together some more introductory docs to suplement the various
   tools / examples.
 * Drop bytes_per_datum sysfs attribute docs as it no longer exists.
 * A whole load of missing / fixing of kernel-doc for the core of IIO.
 * Document the trigger name sysfs attribute in the ABI docs.
 * Minor typos in the ABI docs related to power down modes.

Merge tag 'iio-for-4.3b-2' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

Second set of new device support, features and cleanup for the 4.3 cycle.
Take 2 also includes a fix set that was too late for the 4.2 cycle.

As we had a lot of tools and docs work in this set, I have broken those
out into their own categories in this description.

Fixes from the pull request '4th set of IIO fixes for the 4.2 cycle'.
* Poll functions for both event chardev and the buffer one were returning
  negative error codes (via a positive value).
* A recent change to lsiio adding some error handling that was wrong and
  stopped the tool working.
* bmg160 was missing some dependencies in Kconfig
* berlin2-adc had a misshandled register (wrote a value rather than a bitmap)

New device support
* TI opt3001 light sensor
* TXC PA12 ALS and proximity sensor.
* mcp3301 ADC support (in mcp320x driver)
* ST lsm303agr accelerometer and magnetometer drivers (plus some st-sensors
  common support to allow different WHOAMI register addresses, devices with
  fixed scale and allow interrupt equiped magnetometers).
* ADIS16305, ADIS16367, ADIS16445IMUs (in the adis16400 driver)
* ADIS16266 gyro (in the adis16260 driver)
* ADIS16137 gyro (in the adis16136 driver)

New functionality
* mmc35240 DT bindings.
* Inverse unit conversion macros to aid handing of values written to sysfs
  attributes.

Core cleanup
* Forward declaration of struct iio_trigger to avoid a compile warning.

Driver cleanup / fixes
* mxs-lradc
  - Clarify which parts are supported.
  - Fix spelling erorrs.
  - Missing/extra includes
  - reorder includes
  - add datasheet name listings for all usable channels (to allow them
    to be bound by name from consumer drivers)
* acpi-als - add some function prefixes as per general iio style.
* bmc150_magn - replace a magic value with the existing define.
* vf610 - determine possible sample frequencies taking into account the
  electrical characteristics (defining a minimum sample time)
* dht11
  - whitespace
  - additional docs
  - avoid mulitple assignments in one line
  - Use the new funciton ktime_get_resolution_ns to cleanup a nasty trick
    previously used for timing.
* Fix all drivers that consider 0 a valid IRQ for historical reasons.
* Export I2C module alias info where previously missing (to allow autoprobing)
* Export OF module alias info where previously missing.
* mmc35240 - switch some variables into arrays to improve readability.
* mlx90614 - define some magic numbers for readability.
* bmc150_magn
  - expand area locked by a mutex to cover all the use of the
    data->buffer.
  - use descriptive naming for a mask instead of a magic value.
* berin2-adc
  - pass up an error code rather that a generic error
  - constify the iio_chan_spec
  - some other little tidy ups.
* stk8312
  - fix a dependency on triggered buffers in kconfig
  - add a check for invalid attribute values
  - improve error handling by returning error codes where possible and
    return immediately where relevant
  - rework macro defs to use GENMASK etc
  - change some variable types to reduce unnecessary casting
  - clean up code style
  - drop a local buffer copy for bulk reads and use the one in data->buffer
     instead.
* adis16400 - the adis16448 gyroscope scale was wrong.
* adis16480 - some more wrong scales for various parts.
* adis16300 - has an undocumented product id and serial number registers so
  use them.
* iio_simple_dummy - fix some wrong code indentation.
* bmc150-accel - use the chip ID to detect the chip present rather than
  verifying the expected part was there.  This was in response to a wrong
  ACPI entry on the WinBook TW100.
* mma8452
  - fix _get_hp_filter_index
  - drop a double include
  - pass up an error code rather than rewriting it
  - range check input values to attribute writes
  - register defs tidy up using GENMASK and reordering them to be easier to
    follow.
  - various coding style cleanups
  - put the Kconfig entry in the write place (alphabetically).

Tools related
* Tools cleanup - drop an explicity NULL comparison, some unnecessary braces,
  use the ARRAY_SIZE macro, send error messages to stderr instead of dropping
  them in the middle of normal output.
* Fix tools to allow that scale and offset attributes are optional.
* More tools fixes including allowing true 32bit data (previously an overflow
  prevented more than 31bits)
* Drop a stray header guard that ended up in a c file.
* Make calc_digits static as it isn't exported or in the header.
* Set ci_array pointer to NULL after free as a protection against non safe
  usage of the tools core code.  Also convert a double pointer to a single
  one as the extra level of indirection was unnecessary.

Docs
* DocBook introduction by Daniel Baluta.  Glad we are beginning to
  draw together some more introductory docs to suplement the various
  tools / examples.
* Drop bytes_per_datum sysfs attribute docs as it no longer exists.
* A whole load of missing / fixing of kernel-doc for the core of IIO.
* Document the trigger name sysfs attribute in the ABI docs.
* Minor typos in the ABI docs related to power down modes.

af255cd562 iio: lsiio: fix error code handling error
commit acf50b3586
"tools:iio:lsiio: add error handling"
introduced error handling of errors returned from
read_sysfs_string(), but with a simple if (retval),
missing the fact that these functions return a positive
value if the read was successful.

As a result lsiio regresses and does not show any
devices on my filesystem. Fix this by checking for
only negative error codes.

Pull MIPS fixes from Ralf Baechle:
 "Another round of MIPS fixes for 4.2.  No area does particularly stand
  out but we have a two unpleasant ones:

   - Kernel ptes are marked with a global bit which allows the kernel to
     share kernel TLB entries between all processes.  For this to work
     both entries of an adjacent even/odd pte pair need to have the
     global bit set.  There has been a subtle race in setting the other
     entry's global bit since ~ 2000 but it take particularly
     pathological workloads that essentially do mostly vmalloc/vfree to
     trigger this.

     This pull request fixes the 64-bit case but leaves the case of 32
     bit CPUs with 64 bit ptes unsolved for now.  The unfixed cases
     affect hardware that is not available in the field yet.

   - Instruction emulation requires loading instructions from user space
     but the current fast but simplistic approach will fail on pages
     that are PROT_EXEC but !PROT_READ.  For this reason we temporarily
     do not permit this permission and will map pages with PROT_EXEC |
     PROT_READ.

  The remainder of this pull request is more or less across the field
  and the short log explains them well"
