Merge tag 'media/v3.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull second set of media updates from Mauro Carvalho Chehab:

 - Move drivers for really old legacy hardware to staging.  Those are
   using obsolete media kAPIs and are for hardware that nobody uses for
   years.  Simply not worth porting them to the new kAPIs.  Of course,
   if anyone pops up to fix, we can move them back from there

 - While not too late, do some API fixups at the new colorspace API,
   added for v3.19

 - Some improvements for rcar_vin driver

 - Some fixups at cx88 and vivid drivers

 - Some Documentation fixups
