Merge tag 'media/v3.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media updates from Mauro Carvalho Chehab:
 - Two new dvb frontend drivers: mn88472 and mn88473
 - A new driver for some PCIe DVBSky cards
 - A new remote controller driver: meson-ir
 - One LIRC staging driver got rewritten and promoted to mainstream:
   igorplugusb
 - A new tuner driver (m88rs6000t)
 - The old omap2 media driver got removed from staging.  This driver
   uses an old DMA API and it is likely broken on recent kernels.
   Nobody cared enough to fix it
 - Media bus format moved to a separate header, as DRM will also use the
   definitions there
 - mem2mem_testdev were renamed to vim2m, in order to use the same
   naming convention taken by the other virtual test driver (vivid)
 - Added a new driver for coda SoC (coda-jpeg)
 - The cx88 driver got converted to use videobuf2 core
 - Make DMABUF export buffer to work with DMA Scatter/Gather and Vmalloc
   cores
 - Lots of other fixes, improvements and cleanups on the drivers.
