IB_NF, NB_IF and IB_IF configured the bc polarity incorrectly. The receive
polarity was set to the same edge as the TX in these cases.

backlight: core: Replace kfree with put_device

As per the comments on device_register, we shouldn't call kfree()
right after a device_register() failure. Instead call put_device(),
which in turn will call bl_device_release resulting in a kfree to the
full structure.

[media] gpsca: remove the risk of a division by zero

As reported by Coverity, there's a potential risk of a division
by zero on some calls to jpeg_set_qual(), if quality is zero.

As quality can't be 0 or lower than that, adds an extra clause
to cover this special case.

drm/tegra: dp: Support address-only I2C-over-AUX transactions

drm/dp/i2c: send bare addresses to properly reset i2c connections (v4)

We need bare address packets at the start and end of
each i2c over aux transaction to properly reset the connection
between transactions.  This mirrors what the existing dp i2c
over aux algo currently does.

This fixes EDID fetches on certain monitors especially with
dp bridges.

v2: update as per Ville's comments
    - Set buffer to NULL for zero sized packets
    - abort the entre transaction if one of the messages fails
v3: drop leftover debugging code
v4: integrate Thierry's comments
    - add comments about address only transactions
    - switch back to i and j

scripts: objdiff: detect object code changes between two commits

objdiff is useful when doing large code cleanups.  For example, when
removing checkpatch warnings and errors from new drivers in the staging
tree.

objdiff can be used in conjunction with a git rebase to confirm that
each commit made no changes to the resulting object code.  It has the
same return values as diff(1).

This was written specifically to support adding the skein and threefish
cryto drivers to the staging tree.  I needed a programmatic way to
confirm that commits changing >90% of the lines didn't inadvertently
change the code.

Temporary files (objdump output) are stored in

  /path/to/linux/.tmp_objdiff

'make mrproper' will remove this directory.

ALSA: ice1712: Fix boundary checks in PCM pointer ops

PCM pointer callbacks in ice1712 driver check the buffer size boundary
wrongly between bytes and frames.  This leads to PCM core warnings
like:

   ALSA pcm_lib.c:352 BUG: pcmC3D0c:0, pos = 5461, buffer size = 5461, period size = 2730

This patch fixes these checks to be placed after the proper unit

update comment before the function as it seems somewhat outdated.
