Commit 40f7090bb1b4 ("Input: elan_i2c_smbus - fix corrupted stack")
fixed most of the functions using i2c_smbus_read_block_data() to
allocate a buffer with the maximum block size. However three
functions were left unchanged:
* In elan_smbus_initialize(), increase the buffer size in the same
way.
* In elan_smbus_calibrate_result(), the buffer is provided by the
caller (calibrate_store()), so introduce a bounce buffer. Also
name the result buffer size.
* In elan_smbus_get_report(), the buffer is provided by the caller
but happens to be the right length. Add a compile-time assertion
to ensure this remains the case.

commit 40f7090bb1b4ec327ea1e1402ff5783af5b35195 upstream.
New ICs (like the one on the Lenovo T480s) answer to
ETP_SMBUS_IAP_VERSION_CMD 4 bytes instead of 3. This corrupts the stack
as i2c_smbus_read_block_data() uses the values returned by the i2c
device to know how many data it need to return.
i2c_smbus_read_block_data() can read up to 32 bytes (I2C_SMBUS_BLOCK_MAX)
and there is no safeguard on how many bytes are provided in the return
value. Ensure we always have enough space for any future firmware.
Also 0-initialize the values to prevent any access to uninitialized memory.

commit 04bb1719c4de94700056241d4c0fe3c1413f5aff upstream.
The touch sensor buttons on Sony VAIO VGN-CS series laptops (e.g.
VGN-CS31S) are a separate PS/2 device. As the MUX is disabled for all
VAIO machines by the nomux blacklist, the data from touch sensor
buttons and touchpad are combined. The protocol used by the buttons is
probably similar to the touchpad protocol (both are Synaptics) so both
devices get enabled. The controller combines the data, creating a mess
which results in random button clicks, touchpad stopping working and
lost sync error messages:
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 4
psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1

and automatic module loading by alias does not work as result.
The -I2C suffix in the device name is superfluous, we know what bus we are
dealing with, so let's drop it. Also, no other driver uses capitals, and
the manufacturer name is normally not included, except in very rare cases
of incompatible name collisions.

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.
The compatible strings don't have a vendor prefix because that's how it's
used currently, and changing this will be a Device Tree ABI break.

commit 293b915fd9bebf33cdc906516fb28d54649a25ac upstream.
Trackpoint buttons detection fails on ThinkPad 570 and 470 series,
this makes the middle button of the trackpoint to not being recogized.
As I don't believe there is any trackpoint with less than 3 buttons this
patch just assumes three buttons when the extended button information
read fails.

commit ec667683c532c93fb41e100e5d61a518971060e2 upstream.
Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits
are indicated as TP. Change the constant to bitwise values.
This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead
of it being identified as "PS/2 Generic Mouse".
