[PATCH v2 00/20] Solve the remaining issues with clang and W=1 on media

[Mauro Carvalho Chehab]

Currently, using clang with W=1 and CONFIG_WERROR causes media to break.
This is reported by builder.linuxtv.org.

This series solve the remaining issues.

v2:
  - Use __always_unused for the code we're keeping
  - Dropped a couple more unused functions
  - Added reviews got from the first submission and addressed some comments.

  media: adv7842: get rid of two unused functions
  media: saa7134-go7007: get rid of to_state() function
  media: davinci: get rid of an unused function

[PATCH v2 18/20] media: mtk-mdp: address a clang warning

[Mauro Carvalho Chehab]

The typecasts at the dvb-core generate clang warnings when W=1
is enabled.

Such warning is harmless, but it causes the build to break with
CONFIG_WERROR and W=1 with clang, so do the cast on a way that
it won't produce warnings anymore.
