Merge tag 'media/v4.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 - fix a regression on tvp5150 causing failures at input selection and
   image glitches

 - CEC was moved out of staging for v4.10. Fix some bugs on it while not
   too late

 - fix a regression on pctv452e caused by VM stack changes

 - fix suspend issued with smiapp

 - fix a regression on cobalt driver

 - fix some warnings and Kconfig issues with some random configs.
