Since this driver only defines ->vidioc_try_fmt_vid_cap() the checks can be removed from vidioc_reqbufs(), vidioc_qbuf(), and vidioc_dqbuf(). The ->vidioc_(s|g|try|enum)_fmt_vid_cap() methods are only called on VIDEO_CAPTURE buffers. Thus, there is no need to check or set the buffer's 'type' field since it must already be set to VIDEO_CAPTURE. So setting the buffer type in vidioc_enum_fmt_vid_cap() can be removed.
