Bug description:
  In commit 9958d30f38b9 ("media: Kconfig: cleanup VIDEO_DEV
  dependencies"), VIDEO_V4L2 is now obsoleted and VIDEO_DEV should be
  used instead. This fails the added grep statement in bug 1964484
  evaluates to empty as always, and BUILD_EXCLUSIVE_KERNEL is therefore
  always set on those should not. The error messages will be like:
