Merge branch 'patchwork' into v4l_for_linus

* patchwork: (404 commits)
  [media] uvcvideo: add support for VIDIOC_QUERY_EXT_CTRL
  [media] uvcvideo: fix cropcap v4l2-compliance failure
  [media] media: omap3isp: remove unused clkdev
  [media] coda: Add tracing support
  [media] coda: drop dma_sync_single_for_device in coda_bitstream_queue
  [media] coda: fix fill bitstream errors in nonstreaming case
  [media] coda: call SEQ_END when the first queue is stopped
  [media] coda: fail to start streaming if userspace set invalid formats
  [media] coda: remove duplicate error messages for buffer allocations
  [media] coda: move parameter buffer in together with context buffer allocation
  [media] coda: allocate bitstream buffer from REQBUFS, size depends on the format
  [media] coda: allocate per-context buffers from REQBUFS
  [media] coda: use strlcpy instead of snprintf
  [media] coda: bitstream payload is unsigned
  [media] coda: fix double call to debugfs_remove
  [media] coda: check kasprintf return value in coda_open
  [media] coda: bitrate can only be set in kbps steps
  [media] v4l2-mem2mem: no need to initialize b in v4l2_m2m_next_buf and v4l2_m2m_buf_remove
  [media] s5p-mfc: set allow_zero_bytesused flag for vb2_queue_init
  [media] coda: set allow_zero_bytesused flag for vb2_queue_init
