Merge tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull missed media updates from Mauro Carvalho Chehab: "It seems I screwed-up my previous pull request: it ends up that only half of the media patches that were in linux-next got merged in -rc1. The script which creates the signed tags silently failed due to 5.19->6.0 so it ended generating a tag with incomplete stuff. So here are the missing parts: - a DVB core security fix - lots of fixes and cleanups for atomisp staging driver - old drivers that are VB1 are being moved to staging to be deprecated - several driver updates - mostly for embedded systems, but there are also some things addressing issues with some PC webcams, in the UVC video driver" * tag 'media/v6.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (163 commits) media: sun6i-csi: Move csi buffer definition to main header file media: sun6i-csi: Introduce and use video helper functions media: sun6i-csi: Add media ops with link notify callback media: sun6i-csi: Remove controls handler from the driver media: sun6i-csi: Register the media device after creation media: sun6i-csi: Pass and store csi device directly in video code media: sun6i-csi: Tidy up video code media: sun6i-csi: Tidy up v4l2 code media: sun6i-csi: Tidy up Kconfig media: sun6i-csi: Use runtime pm for clocks and reset media: sun6i-csi: Define and use variant to get module clock rate media: sun6i-csi: Always set exclusive module clock rate media: sun6i-csi: Tidy up platform code media: sun6i-csi: Refactor main driver data structures media: sun6i-csi: Define and use driver name and (reworked) description media: cedrus: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-rotate: Add a Kconfig dependency on RESET_CONTROLLER media: sun8i-di: Add a Kconfig dependency on RESET_CONTROLLER media: sun4i-csi: Add a Kconfig dependency on RESET_CONTROLLER media: sun6i-csi: Add a Kconfig dependency on RESET_CONTROLLER ...
