There are newer controls (V4L2_CID_PAN*, V4L2_CID_TILT*) that provide
similar functionality.

+What: Using V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags
+ to indicate a V4L2 memory-to-memory device capability
+When: 3.8
+Why: New drivers should use new V4L2_CAP_VIDEO_M2M capability flag
+ to indicate a V4L2 video memory-to-memory (M2M) device and
+ applications can now identify a M2M video device by checking
+ for V4L2_CAP_VIDEO_M2M, with VIDIOC_QUERYCAP ioctl. Using ORed
+ V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT flags for M2M
+ devices is ambiguous and may lead, for example, to identifying
+ a M2M device as a video capture or output device.

Identifying a memory-to-memory video device through an ORed output and capture capability flags is not reliable. Schedule this for removal.
