when simulating a storm of fake GUS interrupts (without actually owning
this venerable piece of ISA hardware) the driver falls over (crashes) in
two ways:
1) spinlocks being initialized too late:
INFO: trying to register non-static key.
the code is fine but needs lockdep annotation.
turning off the locking correctness validator.

The polling loop to check for ACI to go down was more convoluted than it
needed to be. New loop should be more efficient and it is a lot simpler. The
old loop checked for a timeout before checking for ACI down, which could
result in an erroneous timeout. It's only a failure if the timeout expires
_and_ ACI is still high. There is nothing wrong with the timeout expiring
while the task is sleeping if ACI went low.
A polling loop to check for the device to leaving INIT mode is removed. The
device must have already left init for the previous ACI loop to have finished.

Fix schedule_timeout() use in alsa-kernel. Mostly just
schedule_timeout(1) --> schedule_timeout_uninterruptible(1)
The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main,
delete a superfluous set_current_state() and in soc/soc-dapm.c replace an
_interruptible with _uninterruptible in some debug code; it's not waiting
for signals.

The OPTi ISA-PnP chips advertise their OPL4 base at 0x380 (to 0x3f0) through
pnp and put their on-chip OPL3 at +8. The driver assumes the provided
value is the ALBase (OPL3 address) though and checks for an OPL4 at -8,
which means that simply adding 8 to the pnp provides value works to fix
detection of both OPL3 and OPL4.
Problem spotted on 931 and 933 by Krzysztof Helt and confirmed on 924 and
925 (together all OPTi ISA-PnP chips) by me.

When the ad1848/cs2431 is first being initialized, auto-calibration may not
be set causing a timeout waiting for it in snd_ad1848/cs4231_mce_down().
This has no dire consequences other than an alarming printk, but since what
we need to wait for is for the calibration to _finish_, let's just check for
that instead.
The early chips need a slight delay (as commented -- 5 sample periods) to be
sure that _if_ calibration is going to happen, it has started when we check
While the CS4231A datasheet implies it'll happen immediately on downing MCE,
some testing is showing that there's a window there as well, so just do the
delay everywhere.
Thanks to Krysztof Helt for pinpointing this problem.

driver already handles the MPU-401 device being unavailable due to lack of
