Thanks for the pointer.

Hmm, right, given that there's no "DOC:" line in intel_guc_fw.c anymore,
the ":doc:" directive above is not useful.

As a tiny step towards more complete documentation (and to keep people
from patching this spot again ;), IMHO it makes sense to do this (it's
of course up to the maintainers whether they agree):

Makes sense.
