[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).
