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: - a new jpeg codec driver for Samsung Exynos (jpeg-hw-exynos4) - a new dvb frontend for ds2103 chipset (m88ds2103) - a new sensor driver for Samsung S5K5BAF UXGA (s5k5baf) - new drivers for R-Car VSP1 - a new radio driver: radio-raremono - a new tuner driver for ts2022 chipset (m88ts2022) - the analog part of em28xx is now a separate module that only load/runs if the device is not a pure digital TV device - added a staging driver for bcm2048 radio devices - the omap 2 video driver (omap24xx) was moved to staging. This driver is for an old hardware and uses a deprecated Kernel internal API. If nobody cares enough to fix it, it would be removed on a couple Kernel releases - the sn9c102 driver was moved to staging. This driver was replaced by gspca, and disabled on some distros, as almost all devices are known to work properly with gspca. It should be removed from kernel on a couple Kernel releases - lots of driver fixes, improvements and cleanups * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (421 commits) [media] media: v4l2-dev: fix video device index assignment [media] rc-core: reuse device numbers [media] em28xx-cards: properly initialize the device bitmap [media] Staging: media: Fix line length exceeding 80 characters in as102_drv.c [media] Staging: media: Fix line length exceeding 80 characters in as102_fe.c [media] Staging: media: Fix quoted string split across line in as102_fe.c [media] media: st-rc: Add reset support [media] m2m-deinterlace: fix allocated struct type [media] radio-usb-si4713: fix sparse non static symbol warnings [media] em28xx-audio: remove needless check before usb_free_coherent() [media] au0828: Fix sparse non static symbol warning Revert "[media] go7007-usb: only use go->dev after allocated" [media] em28xx-audio: provide an error code when URB submit fails [media] em28xx: fix check for audio only usb interfaces when changing the usb alternate setting [media] em28xx: fix usb alternate setting for analog and digital video endpoints > 0 [media] em28xx: make 'em28xx_ctrl_ops' static em28xx-alsa: Fix error patch for init/fini [media] em28xx-audio: flush work at .fini [media] drxk: remove the option to load firmware asynchronously [media] em28xx: adjust period size at runtime ...
