We don't want the writeback triggered from the journal commit (in
data=writeback mode) to cause the journal to abort due to
generic_writepages() returning an ENOMEM error. In addition, if
fsync() fails with ENOMEM, most applications will probably not do the
right thing.
So if we are doing a data integrity sync, and ext4_encrypt() returns
ENOMEM, we will submit any queued I/O to date, and then retry the
allocation using GFP_NOFAIL.

In synaptics_dsx_2.6 touch driver, secure_touch_init tries to get
the QUP clocks for the secure touch functionality. But as these
calls are optional and TZ might get the owenership of these clocks,
this change removes the error return statement, so that the
secure touch can be initialized properly.

If the following call chain fails
adf_device_post_nocopy() ->
adf_buffer_map() ->
dma_buf_attach(); dma_buf_map_attachment()
then the attachment returned by dma_buf_attach() will get cleaned up
twice: first during the error-handling path inside adf_buffer_map(), and
again during the error-handling path inside adf_device_post_nocopy().
Fix this by zeroing out the mapping data inside adf_buffer_map()'s
error-handling path. When adf_device_post_nocopy() hands it back to
adf_buffer_mapping_cleanup(), it will deliberately skip over zeroed-out
data.
(The second adf_buffer_mapping_cleanup() call inside
adf_device_post_nocopy() is not a bug; it's intended to clean up after
any *other* buffers we handled as part of this request.)

Add support to indicate if the switcher is acting in input limited state.
Switcher running in high duty cycle (HDC) mode should also be indicated as
input limited condition.
HDC is a 5uS pulse and sw reading the real time status register may not
indicate that it is active. Basically the presence of the pulses and the
interrupts indicate HDC and conversely their absence indicates no
HDC. Set a flag in the interrupt and clear it in a delayed work queue in
20mS. As long as the interrupts happen this flag will remain set,
indicating HDC.

Make sure to only call regulator_disable() on VCONN only if
it was previously enabled, else it could result in an
unbalanced disable state. Subsequent enables would then be
no-ops and the regulator would not actually turn on.
