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

-/*
-	Supported devices:
-	*Lifeview FlyCam Supra (using the Philips saa7111a chip)
-
-	Does any other model using the w9966 interface chip exist ?
-
-	Todo:
-
-	*Add a working EPP mode, since DMA ECP read isn't implemented
-	in the parport drivers. (That's why it's so sloow)
-
-	*Add support for other ccd-control chips than the saa7111
-	please send me feedback on what kind of chips you have.
-
-	*Add proper probing. I don't know what's wrong with the IEEE1284
-	parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
-	and nibble read seems to be broken for some peripherals.
-
-	*Add probing for onboard SRAM, port directions etc. (if possible)
-
-	*Add support for the hardware compressed modes (maybe using v4l2)
-
-	*Fix better support for the capture window (no skewed images, v4l
-	interface to capt. window)
-
-	*Probably some bugs that I don't know of
-
-	Please support me by sending feedback!
-
-	Changes:
-
-	Alan Cox:	Removed RGB mode for kernel merge, added THIS_MODULE
-			and owner support for newer module locks
