Thnaks for the very quick response.

Please provide a changelog so we can follow what has changed.
Sometimes we revisit patches week and 100 patches later and cannot
remember any feedback.

Like for example (my style):
v3:
  - fixed checkpatch warnings (sam)
  - ...

v2:
  - dropped backlight (sam)
  - dropped kernel-doc (sam)
  - bla bla (someone)

There are many different styles - pick one.



Also two other things.
checkpatch --strict reports a few issues to be fixed:

    total: 0 errors, 5 warnings, 6 checks, 344 lines checked

One of them is a missing binding!

And the patch fails to apply. Please rebase on top of -next or
drm-misc-next.

Thanks in advance!
