The documentation seems fine to me (except for one comment below). However,
converting macros to an enum just to work around a defect of the documentation
system doesn't seem like a good idea to me. I'd rather find a way to document
macros.

s/BUFF/BUF.
A regexp would use VIDIOC_(Q|DQ)BUF. You can also write VIDIOC_{QBUF,DQBUF}
which seems clearer to me.
