Merge tag 'media/v5.8-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull more media updates from Mauro Carvalho Chehab:
- a set of atomisp patches. They remove several abstraction layers, and
fixes clang and gcc warnings (that were hidden via some macros that
were disabling 4 or 5 types of warnings there). There are also some
important fixes and sensor auto-detection on newer BIOSes via ACPI
_DCM tables.
- some fixes
