I get that way sometimes too; sigh.  Can't stay that way though,
for better or worse.

Yes, I'll do that.  Some of them are bugfixes that should go in.

(And I just sent one *new* patch, which should go in, finally
making the DaVinci stuff work in mainline.  Previous build fixes
behaved correctly, but init tweaks are needed too.)

It's one driver that runs on a boatload of different silicon
so it needs to be changed with some caution.  Despite the fact
that the original code from Mentor was deeply crapulous, and
not all of the goofage has been removed.  (Arguably, not all
of it *can* be removed; they invented their own OTG state
machine, which doesn't match the USB-IF specs...)

Which means that unlike most low level USB drivers, it's got
folk from several teams working concurrently:  one from Analog,
two or three from TI, one from MontaVista, a couple from Nokia.

Thankfully it's not as bad as the mess we had with UHCI in
the 2.4 kernel days; most developers are happy to cooperate
and just get the bugs fixed.  But with that many people at
work on some nasty problems, some friction on both technical
and personal levels is probably inevitable.
