Merge tag 'media/v4.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab:
- a new frontend driver for new ATSC devices: lgdt3306a
- a new sensor driver: ov2659
- a new platform driver: xilinx
- the m88ts2022 tuner driver was merged at ts2020 driver
- the media controller gained experimental support for DVB and hybrid
devices
- lots of random cleanups, fixes and improvements on media drivers
