Merge branch 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media into next

Pull media updates from Mauro Carvalho Chehab: "This contains: - a new frontend/tuner driver set for si2168 and sa2157 - Videobuf 2 core now supports DVB too - A new gspca sub-driver (dtcs033) - saa7134 is now converted to use videobuf2 - add support for 4K timings - several other driver fixes and improvements PS. This pull request is shorter than usual, partly because I have some other patches on topic branches that I'll be sending you later this week" * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (286 commits) [media] au0828-dvb: restore its permission to 644 [media] xc5000: delay tuner sleep to 5 seconds [media] xc5000: Don't use whitespace before tabs [media] xc5000: fix CamelCase [media] xc5000: Don't wrap msleep() [media] xc5000: get rid of positive error codes [media] au0828: reset streaming when a new frequency is set [media] au0828: Improve debug messages for urb_completion [media] au0828: Cancel stream-restart operation if frontend is disconnected [media] dib0700: fix RC support on Hauppauge Nova-TD [media] USB: as102_usb_drv.c: Remove useless return variables [media] v4l: Fix documentation of V4L2_PIX_FMT_H264_MVC and VP8 pixel formats [media] m5mols: Replace missing header [media] staging: lirc: Fix sparse warnings [media] fix mceusb endpoint type identification/handling [media] az6027: Added the PID for a new revision of the Elgato EyeTV Sat DVB-S Tuner [media] DocBook media: fix typo [media] adv7604: Add missing include to linux/types.h [media] v4l: Validate fields in the core code for subdev EDID ioctls [media] v4l: Add support for DV timings ioctls on subdev nodes ...
