Merge tag 'media/v5.1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:

 - remove the deprecated Zoran driver from staging

 - new I2C driver: ST MIPID02 CSI-2 camera bridge

 - new platform driver: Amlogic Meson AO CEC G12A Controller

 - add support for USB audio via the media controller

 - au0828 driver is now supported via the media controller on both on
   media and on usbaudio

 - new kernel test for the media device allocator

 - add support for stateless decoder at vicodec driver

 - lots of other driver improvements fixes and cleanups
