Will look into it, that does sound like a nicer solution. Thanks!

Ah yeah I was going back and forth between matching this within the
series vs matching the subsystem. I guess going with the subsystem is
mote important long term.

That is very strange. I did run checkpatch before. There are a few
warnings not to touch obsolete code unnecessarily and a check about
using udelay() (pre-existing) plus two missing blank lines in pci-
quirks.h that I ignored because it matches the sorounding style.
I did notice that lore fails to render the subject lines for some of
the patches. But I just tried fetching the patches with b4 on top of
v5.16-rc7 and the resulting tree passes "./scripts/checkpatch.pl --git
v5.16-rc7..HEAD" and has an empty diff to my branch. What tool did you
use to check?
