The patch you were reviewing does not have pr_* stuff included, sorry.
I published V3 by mistake missing some changes. Patch V3.1 alreay
fixes that.

That magic hex values always match common name of chipsets, so it's
looks pretty clean/obvious... Not sure if it's worth it?

for the chipsets, they invented sth like 43224 but they had only
0xFFFF. So the used 0xA8D8==43224.
