When true, it causes the function to copy the V4L2_BUF_FLAG_KEYFRAME, V4L2_BUF_FLAG_BFRAME and V4L2_BUF_FLAG_PFRAME flags from the output buffer to the capture buffer. There is no use cases in any upstream driver for copying the flags. KEY/P/B frames are properties of the bitstream buffer in some formats. Once decoded, this is no longer a property of the video frame and should be discarded. It was considered useful to know if an uncompressed frame was decoded from a KEY/P/B compressed frame, and to preserve that information if that same uncompressed frame was passed through another M2M device (e.g. a scaler). However, the V4L2 documentation makes it clear that the flags are meant for compressed frames only. Drop the copy_frame_flags argument from v4l2_m2m_buf_copy_metadata(). The change to drivers was performed with the following Coccinelle semantic patch: @@ expression src; expression dst; expression flag; @@ - v4l2_m2m_buf_copy_metadata(src, dst, flag); + v4l2_m2m_buf_copy_metadata(src, dst); include/media/v4l2-mem2mem.h and drivers/media/v4l2-core/v4l2-mem2mem.c have been updated manually.

Replace all remaining locations that read the v4l2_fh pointer directly from file->private_data and cast it to driver-specific file handle structures with driver-specific functions that use file_to_v4l2_fh() and perform the same cast. No functional change is intended, this only paves the way to remove direct accesses to file->private_data and make V4L2 drivers safer. Other accesses to the field will be addressed separately.
