Merge tag 'media/v5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 - a rand Kconfig fixup for mtk-vcodec

 - a fix at h264 handling at cedrus codec driver

 - some warning fixes when config PM is not enabled at marvell-ccic

 - two fixes at venus codec driver: one related to codec profile and the
   other one related to a bad error path which causes an OOPS on module
   re-bind
