Merge tag 'media/v4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:
 "Some bug fixes:

   - Don't fail build if atomisp has warnings

   - Some CEC Kconfig changes to allow it to be used by DRM without
     media dependencies

   - A race fix at RC initialization code

   - A driver fix at rainshadow-cec

  IMHO, the one that affects most people in this series is a build fix:
  if you try to build the Kernel with W=1 or using gcc7 and
  all[yes|mod]config, build will fail due to -Werror at atomisp
  makefiles"

* tag 'media/v4.12-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
  [media] rc-core: race condition during ir_raw_event_register()
  [media] cec: drop MEDIA_CEC_DEBUG
  [media] cec: rename MEDIA_CEC_NOTIFIER to CEC_NOTIFIER
  [media] cec: select CEC_CORE instead of depend on it
  [media] rainshadow-cec: ensure exit_loop is intialized
  [media] atomisp: don't treat warnings as errors
