Merge tag 'media/v4.6-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab: "Some bug fixes on au0828 and snd-usb-audio: - the au0828+snd-usb-audio MC patch broke several things and produced some race conditions. Better to revert the patches, and re-work on them for a next version - fix a regression at tuner disable links logic - properly handle dev_state as a bitmask" * tag 'media/v4.6-3' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] Revert "[media] media: au0828 change to use Managed Media Controller API" [media] Revert "[media] sound/usb: Use Media Controller API to share media resources" [media] au0828: Fix dev_state handling [media] au0828: fix au0828_v4l2_close() dev_state race condition [media] media: au0828 fix to clear enable/disable/change source handlers [media] v4l2-mc: cleanup a warning [media] au0828: disable tuner links and cache tuner/decoder
