Several of the comments in this file do appear to be kerneldoc (in fact
kerneldoc that was specifically requested during code review at
https://patchwork.freedesktop.org/patch/448456/#comment_804252) and this
file is included from Documentation/gpu/i915.rst, so I think some of
these changes might be moving in the wrong direction. Should we instead
focus on fixing up the comments that aren't quite formatted properly?
