I think the commit message would be enough so we know which device
we're talking about, but now that you mention it, maybe the source code
would be a good idea too.

As far as I've understood, and Benjamin can correct me, we don't need
to have IDs be in hid-ids.h because we don't need to declare them both
as a blocklist in the hid core, and then again in the driver itself.

My take is that the patches could move the IDs from hid-ids.h to hid-
microsoft.c as they're changed. You then wouldn't need the macros, just
add a comment for each of variants, and that Wikipedia article can be
linked above the whole XBox controller section.

What do you think?
