Subject: libcamera: v4l2_device: Update dequeued buffer information
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Copy the information from the struct v4l2_buffer when dequeueing the
buffer as applications need this information to make sense of the
captured data.
