Sergei Shtylylov 7b6666530e [PATCH] Au1550 AC'97 OSS driver spinlock fixes 
We have found some issues with Au1550 AC'97 OSS driver in 2.6
(sound/oss/au1550_ac97.c), though it also should concern 2.4 driver
(drivers/sound/au1550_psc.c).

start_dac() grabs a spinlock already held by its caller, au1550_write().
This doesn't show up with the standard UP spinlock impelmentation but when
the different one (mutex based) is in use, a lockup happens.

And the interrupt handlers also didn't grab the spinlock -- that's OK in
the usual kernel but not when the IRQ handlers are threaded.  So, they're
grabbing the spinlock now (as every correct interrupt handler should do).

README.FIRST 

The modular sound driver patches were funded by Red Hat Software 
(www.redhat.com). The sound driver here is thus a modified version of 
Hannu's code. Please bear that in mind when considering the appropriate
forums for bug reporting.
