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.

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.

When a machine goes to S3/S4 after power-save is enabled, the runtime
PM refcount might be incorrectly decreased because the power-down
triggered soon after resume assumes that the controller was already
powered up, and issues the pm_notify down.
This patch fixes the incorrect pm_notify call simply by checking the
current value properly.

The pcm_usb_stream plugin requires the mremap explicitly for the read
buffer, as it expands itself once after reading the required size.
But the commit [314e51b9: mm: kill vma flag VM_RESERVED and
mm->reserved_vm counter] converted blindly to a combination of
VM_DONTEXPAND | VM_DONTDUMP like other normal drivers, and this
resulted in the failure of mremap().
For fixing this regression, we need to remove VM_DONTEXPAND for the
read-buffer mmap.

The create_bind_cap_vol_ctl does not create any control indicating
that an inverted dmic is present. Therefore, create multiple
capture volumes in this scenario, so we always have some indication
that the internal mic is inverted.
This happens on the Lenovo Ideapad U310 as well as the Lenovo Yoga 13
(both are based on the CX20590 codec), but the fix is generic and
could be needed for other codecs/machines too.
Thanks to Szymon Acedański for the pointer and a draft patch.

essentially disabling the internal mic. Therefore turn off presence

Note: The external mic seems not yet working, but an internal mic is
certainly better than no mic at all.

Currently hdmi_setup_audio_infoframe() reprograms the HDA channel
mapping only when the infoframe is not up-to-date or the non-PCM flag
has changed.
However, when just the channel map has been changed, the infoframe may
still be up-to-date and non-PCM flag may not have changed, so the new
channel map is not actually programmed into the HDA codec.
Notably, this failing case is also always triggered when the device is
already in a prepared state and a new channel map is configured while
changing only the channel positions (for example, plain
"speaker-test -c2 -m FR,FL").
Fix that by always programming the channel map in
hdmi_setup_audio_infoframe(). Tested on Intel HDMI.
