There is a code sequence where the locking is substream->self_group.lock
-> ins->scbs[index].lock
substream->self_group.lock is interrupt safe, and taken from irq context
as well (trace is snipped for brevity)
so what can happen is
cpu 0 cpu 1
user context user context
take ins->scbs[index].lock without disabling interrupts
get substream->self_group.lock (irqsafe)
try to get ins->scbs[index].lock (spins)
interrupt happens
try to get substream->self_group.lock (spins)
which is an obvious AB-BA deadlock
fix is to just take the lock with _irqsafe

This patch adds two mixer controls. The V_REFOUT enable is a
documented register that couples the microphone input lines
to the V_REFOUT DC source. The High Pass Filter enable in the
AC97_AD_TEST2 (0x5c) is an undocumented register provided by
Miller Puckette via Analog Devices that enables the AD codec
to apply a high pass filter to the input.

Christian Bjalevik reports in LP#38546 that his sound chipset requires
the 'hp_only' quirk to allow him to control sound volume correctly when
headphones are inserted. This patch adds the appropriate pci id to the
via82xx ALSA driver so that the quirk is applied automatically, thereby
removing the need for users to modify /etc/modprobe.d/alsa-base (or to
unload and reload snd-via82xx with ac97_quirk=hp_only).
This patch closes LP#38546.

This patch conditions AC97 control creation by whether or not the
codec is an AD18xx codec. This fixes the case where the default control
would get created and then snd_ac97_mixer_build fails out when creation
of ad18xx specific control would get attempted. This problem was found
and debuged by Marcelo Tosatti.
