If spin_lock_irqsave is called twice in a row with the same second
argument, the interrupt state at the point of the second call overwrites
the value saved by the first call. Indeed, the second call does not need
to save the interrupt state, so it is changed to a simple spin_lock.
The semantic match that finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)
// <smpl>
@@
expression lock1,lock2;
expression flags;
@@
*spin_lock_irqsave(lock1,flags)
... when != flags
*spin_lock_irqsave(lock2,flags)
// </smpl>

Adding MPU-401 support to cmi8330 driver could cause a regression (non-working
sound) on a system where there is no free IRQ for the MPU-401 device (which
is not very uncommon as this card requires two separate IRQs plus a third one
for MPU-401).
When MPU-401 PnP configuration fails (mostly because of unavailable IRQ), just
ignore MPU-401 and continue without it.

My CMI8329 had OPL3 port specified in SB16 resources. But now I found out that
it was my modification of the card's PnP EEPROM a couple of years ago (can be
done using C9SETROM.EXE utility). I did it because the OPL3 port was
completely missing from PnP data. It seems to be hardwired to 0x388 on
CMI8329.
Find OPL3 port automatically by searching in WSS and SB16 resources. If not
found, assume that it's hardwired to 0x388.

Add basic support for CMI8329 cards. Makes PCM and OPL3 work.
Does not break CMI8330 (tested).

In ALSA 1.0.20, the comments were changed to say CMI8330 instead of AD1848.
The CMI8330 chip includes two codecs - AD1848 and SB16, so the comments were
correct and are misleading now. Revert them back.

3 ISA sound drivers lack their __devexit_p() markers, which would
cause build failures when the kernel is built without hotplug support.
