ALSA: hda - Fix invalid snd_BUG_ON() in alc271_hp_gate_mic_jack()

The fixup function is called multiple times before parsing the pins,
so snd_BUG_ON() hits when loaded.  Move it to the proper place in the
if block.

ALSA: hda - Fix inconsistent pin states after resume

The commit [26a6cb6c: ALSA: hda - Implement a poll loop for jacks as a
module parameter] introduced the polling jack detection code, but it
also moved the call of snd_hda_jack_set_dirty_all() in the resume path
after resume/init ops call.  This caused a regression when the jack
state has been changed during power-down (e.g. in the power save
mode).  Since the driver doesn't probe the new jack state but keeps
using the cached value due to no dirty flag, the pin state remains
also as if the jack is still plugged.

The fix is simply moving snd_hda_jack_set_dirty_all() to the original
position.

ALSA: hda - Fix missing path between aamix and outputs in AD codecs

AD1988 family and AD1882 codecs have another mixer widget (0x21)
between the analog-loopback mixer widget (0x20) and the actual
outputs.  Due to this hole, the analog-loopbacks aren't sent properly
to the output pins.

As a band-aid fix, introduce another fields holding the aamix merge
path, and activate it.

ALSA: hda - Add chained_before flag to the fixup entry

Sometimes we want to call a fixup after applying other existing
fixups, but currently the fixup chain mechanism allows only the call
the others after the target fixup.  This patch adds a new flag,
chained_before, to struct hda_fixup, for allowing the chained call
before the current execution.

ALSA: hda - Add a fixup for Packard-Bell desktop with ALC880

A Packard-Bell desktop machine gives no proper pin configuration from
BIOS.  It's almost equivalent with the 6stack+fp standard config, just
take the existing fixup.

Merge branch 'for-linus' into for-next

Merge the 3.8 devel branch for correcting the newly added PB desktop
fixup with the automute support.
ALSA: hda - Add auto-mute support to PB desktop

Using the new chained_before flag, we can correct the headphone jack
detection capability easily over the existing ALC880 6stack model
(which disables the jack detection intentionally for compatibility
reason).

ALSA: hda - Fix wrong arguments for path deactivation checks

The arguments to call is_active_nid() in activate_amp() were swapped,
and this resulted in the muted amp on some SPDIF output pins.

Also, the index to be passed to is_active_nid() must be idx_to_check.
Otherwise it checks the wrong connection in the case of implicit aamix
connection paths.

ALSA: hda/via - Fix wrong checks of power state bits

AC_VERB_GET_POWER_STATE returns the combined bits of the actual state
and the target state.  Thus, comparing the obtained value directly
with the target value can't work.  The value has to be shifted and
masked properly.

ALSA: hda - Add power state filtering

Add a hook to struct hda_codec for filtering the target power state of
each widget when powering up/down.  The current hackish EAPD check is
implemented as the default hook pointer, too.

This allows codec drivers to implement own power filter.  In the
upcoming changes, the generic parser will have the better power filter
based on the active paths.

ALSA: hda - Synchronize the power state at the end of codec init

Put the power state synchronization at the end of the parsing of
codec.  This is necessary when the power filter is changed during the
codec probe.  Since the first power-up sequence is performed without
the special filter, all widgets are supposed to be ON at this point.
