Merge tag 'media/v5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - remove sensor drivers that got converted from soc_camera

 - remaining soc_camera drivers got moved to staging

 - some documentation cleanups and improvements

 - the imx staging driver now supports imx7

 - the ov9640, mt9m001 and mt9m111 got converted from soc_camera

 - the vim2m driver now does what a m2m convert driver expects to do

 - epoll() fixes on media subsystems

 - several drivers fixes, typos, cleanups and improvements
