Subject: [PATCH] docs: make kernel-doc handle varargs properly
As far as I can tell, the handling of "..." arguments has never worked
right, so any documentation provided was ignored in favor of "variable
arguments." This makes kernel-doc handle "@...:" as documented. It does
*not* fix spots in kerneldoc comments that don't follow that convention,
but they are no more broken than before.
