Merge tag 'media/v4.2-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 - a regression fix at the videobuf2 core driver

 - fix error handling at mantis probing code

 - revert the IR encode patches, as the API is not mature enough.
   So, better to postpone the changes to a latter Kernel

 - fix Kconfig breakages on some randconfig scenarios.
