Tomasz Figa 13d93380fc media: Clarify the meaning of file descriptors in VIDIOC_DQBUF 
When the application calls VIDIOC_DQBUF with the DMABUF memory type, the
v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf
file descriptors. However, the current documentation does not explain
whether those are new file descriptors referring to the same DMA-bufs or
just the same integers as passed to VIDIOC_QBUF back in time. Clarify
the documentation that it's the latter.
