In my opinion, reST-specific clutters like these should be avoided in
kernel-doc comments as far as possible.
Instead, I think you can educate kernel-doc (script) so that "*" is
allowed in the %CONSTANT pattern, meaning %WQ_* can be converted
to ``WQ_*`` in reST.
For similar changes made against the @param pattern, see commits
69fc23efc7e5 ("kernel-doc: Add unary operator * to $type_param_ref")
and 8aaf297a0dd6 ("docs: scripts: kernel-doc: accept bitwise negation
like ~@var").
I guess it is $type_constant2 that needs a tweak in this case.
HTH,
