Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - Some cleanups at V4L2 documentation - new drivers: ts2020 frontend, ov9650 sensor, s5c73m3 sensor, sh-mobile veu mem2mem driver, radio-ma901, davinci_vpfe staging driver - Lots of missing MAINTAINERS entries added - several em28xx driver improvements, including its conversion to videobuf2 - several fixups on drivers to make them to better comply with the API - DVB core: add support for DVBv5 stats, allowing the implementation of statistics for new standards like ISDB - mb86a20s: add statistics to the driver - lots of new board additions, cleanups, and driver improvements. * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (596 commits) [media] media: Add 0x3009 USB PID to ttusb2 driver (fixed diff) [media] rtl28xxu: Add USB IDs for Compro VideoMate U620F [media] em28xx: add usb id for terratec h5 rev. 3 [media] media: rc: gpio-ir-recv: add support for device tree parsing [media] mceusb: move check earlier to make smatch happy [media] radio-si470x doc: add info about v4l2-ctl and sox+alsa [media] staging: media: Remove unnecessary OOM messages [media] sh_vou: Use vou_dev instead of vou_file wherever possible [media] sh_vou: Use video_drvdata() [media] drivers/media/platform/soc_camera/pxa_camera.c: use devm_ functions [media] mt9t112: mt9t111 format set up differs from mt9t112 [media] sh-mobile-ceu-camera: fix SHARPNESS control default Revert "[media] fc0011: Return early, if the frequency is already tuned" [media] cx18/ivtv: fix regression: remove __init from a non-init function [media] em28xx: fix analog streaming with USB bulk transfers [media] stv0900: remove unnecessary null pointer check [media] fc0011: Return early, if the frequency is already tuned [media] fc0011: Add some sanity checks and cleanups [media] fc0011: Fix xin value clamping Revert "[media] [PATH,1/2] mxl5007 move reset to attach" ...
