Merge tag 'media/v4.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media
Pull media updates from Mauro Carvalho Chehab: - videobuf2 was moved to a media/common dir, as it is now used by the DVB subsystem too - Digital TV core memory mapped support interface - new sensor driver: ov7740 - several improvements at ddbridge driver - new V4L2 driver: IPU3 CIO2 CSI-2 receiver unit, found on some Intel SoCs - new tuner driver: tda18250 - finally got rid of all LIRC staging drivers - as we don't have old lirc drivers anymore, restruct the lirc device code - add support for UVC metadata - add a new staging driver for NVIDIA Tegra Video Decoder Engine - DVB kAPI headers moved to include/media - synchronize the kAPI and uAPI for the DVB subsystem, removing the gap for non-legacy APIs - reduce the kAPI gap for V4L2 - lots of other driver enhancements, cleanups, etc. * tag 'media/v4.16-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (407 commits) media: v4l2-compat-ioctl32.c: make ctrl_is_pointer work for subdevs media: v4l2-compat-ioctl32.c: refactor compat ioctl32 logic media: v4l2-compat-ioctl32.c: don't copy back the result for certain errors media: v4l2-compat-ioctl32.c: drop pr_info for unknown buffer type media: v4l2-compat-ioctl32.c: copy clip list in put_v4l2_window32 media: v4l2-compat-ioctl32.c: fix ctrl_is_pointer media: v4l2-compat-ioctl32.c: copy m.userptr in put_v4l2_plane32 media: v4l2-compat-ioctl32.c: avoid sizeof(type) media: v4l2-compat-ioctl32.c: move 'helper' functions to __get/put_v4l2_format32 media: v4l2-compat-ioctl32.c: fix the indentation media: v4l2-compat-ioctl32.c: add missing VIDIOC_PREPARE_BUF media: v4l2-ioctl.c: don't copy back the result for -ENOTTY media: v4l2-ioctl.c: use check_fmt for enum/g/s/try_fmt media: vivid: fix module load error when enabling fb and no_error_inj=1 media: dvb_demux: improve debug messages media: dvb_demux: Better handle discontinuity errors media: cxusb, dib0700: ignore XC2028_I2C_FLUSH media: ts2020: avoid integer overflows on 32 bit machines media: i2c: ov7740: use gpio/consumer.h instead of gpio.h media: entity: Add a nop variant of media_entity_cleanup ...
