commit 0e7659712836ca59b4735bc5cc94de38698a5e01 upstream.

The extcon driver takes the DAPM mutex from within the interrupt thread
in several places, which makes it possible to get into a situation where
the interrupt thread is blocked waiting on the DAPM mutex whilst a DAPM
sequence is running which is attempting to configure the FLL. In this
case the FLL completion can't be completed as as the IRQ handler is
ONE_SHOT, which cause the FLL lock to use the full time out (250mS) and
report that the process timed out.

It is not really practical to make the extcon driver not take the DAPM
mutex from within the interrupt thread, at least not without extensive
modification. So this patch fixes the issue by switching the wait for
the FLL lock to polling. A few fast polls are done first as the FLL
should lock quickly for a good quality reference clock, (indeed it hits
on the first poll on my system) and it will poll every 20mS after that
until it times out.

commit 1cf5a330c05ae37a0a98ac7c9800a6f50d5579ec upstream.

The wrong register was used to set the gain of ref loop, when changing
the FLL output on an active FLL. This patch corrects the offset of the
gain register.

commit 14a500fe1396934c6b3ed8f009459a4723da7862 upstream.

There is no use of snd_soc_unregister_card in remove function
as devm_snd_soc_register_card in probe function automatically
handles it. So, remove use of snd_soc_unregister_card and with
this change remove arndale_audio_remove as it is now redundant.

The power for line out was not turned on when line out is enabled.
So we add "LOUT amp" widget to turn on the power for line out.

The widget power-saving code tries to turn up/down the power of each
widget in the I/O paths that are modified at each jack plug/unplug.
The recent report revealed that the power activation leaves some
widgets unpowered after plugging.  This is because
snd_hda_activate_path() turns on path->active flag at the end of the
function while the path power management is done before that.  Then
it's regarded as if nothing is active, and the driver turns off the
power.

The fix is simply to set the flag at the beginning of the function,
before trying to power up.

The is_active_nid_for_any() function in the generic parser is supposed
to check all connections from/to the given widget, but the current
code checks only the first input connection (index = 0).

This patch corrects the code to check all inputs by passing -1 to
index argument.

After a for-loop was replaced by list_for_each_entry, see
Commit bbbc7e8502c9 ("ALSA: hda - Allocate hda_pcm objects dynamically"),
Commit 751e2216899c ("ALSA: hda: fix possible null dereference"),
a possible NULL pointer dereference has been introduced; this patch adds
the NULL check on pcm->pcm, while leaving a potentially superfluous
check on pcm itself untouched.

On shutdown/reboot of CX20722, first shut down all EAPDs, then
shut down the afg node to D3.

Failure to do so can lead to spurious noises from the internal speaker
directly after reboot (and before the codec is reinitialized again, i e
in BIOS setup or GRUB menus).
