USB generic driver
This patch reintroduces the check for endpoint numbers that are
specified explicitly in the quirk structure.
This check was accidentally dropped in the last rewrite of
snd_usbmidi_detect_endpoints().

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!
