This is provoked when the ASoC front end is open along with its backend,
(which causes the backend to have a runtime assigned to it) and then the
SNDRV_CTL_IOCTL_PCM_INFO is requested for the (visible) backend device.
Resolve this by ensuring that ASoC internal backend devices are not
visible to userspace, just as the commentry for snd_pcm_new_internal()
says it should be.

is particularly noticable.
ASUS N76VZ needs the same fixup as N56VZ for supporting the boost
speaker.

AD1984A codec has a couple of pins with EAPD controls, and the generic
codec driver tries to turn each of them on/off depending on the pin
active state. However, Thinkpads seem to use EAPD of the speaker pin
as a master EAPD for controlling the mute of all outputs, including
the headphone. This results in the dead headphone output via the
headphone plugging because it mutes the speaker and turns off EAPD.
The fix is to simply add spec->gen.keep_on_eapd flag.
[This is a regression fix on 3.12 where we moved the AD codec parser
to the generic parser. 3.11 and earlier didn't show this problem
because still static quirks have been used.]

The generic parser has a support of vmaster hook, but this is
initialized only in the init callback with the check of the presence
of the corresponding kctl. However, since kctl is NULL at the very
first init callback that is called before build_controls callback, the
vmaster hook sync is skipped there. Eventually this leads to the
uninitialized state depending on the hook implementation.
This patch adds a simple workaround, just calling the sync function
explicitly at build_controls callback.
