Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media fixes from Mauro Carvalho Chehab:
"For some media fixes:
- dvb_usb_v2: some fixes at the core
- Some fixes on some embedded drivers: soc_camera, adv7604, omap3isp,
exynos/s5p
- Several Exynos4/5 camera fixes
- a fix at stv0900 driver
- a few USB ID additions to detect more variants of rtl28xxu-based
sticks"
