Use the new snd_soc_codec_force_bias_level() helper function to invoke the
bias_level callback of a driver instead of calling the callback by hand.
Currently the effect of this is the same, but having all bias level updates
go through a central place will allow us to move more of the bias level
management into the DAPM core.

Update extcon for v4.1
This patchset include two new extcon driver and fix minor issue of extcon
driver.
Detailed description for patchset:
1. new extcon-max77843.c and extcon-usb-gpio.c extcon driver
- extcon-max77843.c driver support the MAXIM MAX77843 MUIC (Micor-USB Interface
Controller) device which handles the various external connectors such as TA/USB
/USB-HOST/JIG and so on.
- extcon-usb-gpio.c driver support the USB and USB-HOST cable detection by
using the GPIO pin which is connected to USB ID pin. This GPIO pin updates the
USB cable states.
2. Rename the filename of extcon core driver and add missing locking mechanism
- Rename the previous extcon-class driver.c as extcon.c because '-class'
postfix is not necessary word.
- extcon core driver (extcon.c) used the raw_notifier_chain. It must be
protected by locking mechanism to avoid the list changing while
extcon_update_state() is executed.
3. Fix minor issue of extcon drviers
- Fix cable name by using the capital letter instead of small letter on
extcon-max77693.c driver.
- Clean-up code of extcon-arizona.c to detect headphone cable.
- Fix the wrong return type and variable type on extcon-max77843.c.
- Fix the checkpatch warning of all extcon drivers.

arizona_extcon_do_magic does not lend a lot of clarity to the purpose
of the function, and as all the registers used are described in the
datasheet there is no need to obfuscate the code. This patch renames the
function to arizona_extcon_hp_clamp, as it controls clamping on the
headphone output.

Pull sound updates from Takashi Iwai:
"There have been major modernization with the standard bus: in ALSA
sequencer core and HD-audio. Also, HD-audio receives the regmap
support replacing the in-house cache register cache code. These
changes shouldn't impact the existing behavior, but rather
refactoring.
In addition, HD-audio got the code split to a core library part and
the "legacy" driver parts. This is a preliminary work for adapting
the upcoming ASoC HD-audio driver, and the whole transition is still
work in progress, likely finished in 4.1.
Along with them, there are many updates in ASoC area as usual, too:
lots of cleanups, Intel code shuffling, etc.
Here are some highlights:
ALSA core:
- PCM: the audio timestamp / wallclock enhancement
- PCM: fixes in DPCM management
- Fixes / cleanups of user-space control element management
- Sequencer: modernization using the standard bus
HD-audio:
- Modernization using the standard bus
- Regmap support
- Use standard runtime PM for codec power saving
- Widget-path based power-saving for IDT, VIA and Realtek codecs
- Reorganized sysfs entries for each codec object
- More Dell headset support
ASoC:
- Move of jack registration to the card level
- Lots of ASoC cleanups, mainly moving things from the CODEC level to
the card level
- Support for DAPM routes specified by both the machine driver and DT
- Continuing improvements to rcar
- pcm512x enhacements
- Intel platforms updates
- rt5670 updates / fixes
- New platforms / devices: some non-DSP Qualcomm platforms, Google's
Storm platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC
Misc:
- ice1724: Improved ESI W192M support
- emu10k1: Emu 1010 fixes/enhancement"

wait_for_completion_timeout can be called with timeout == 0 due to
msecs_to_jiffies(2) == 1 for HZ < 1000 and usecs_to_jiffies(300) == 1
for all reasonable values of HZ, thus the following timeout /= 2; sets
timeout to 0. This patch simply adds a lower-bounds of 1.

Currently both the oscillator and the PLL are powered up in
set_bias_level. This can be problematic when using output clocks from
the wm8804 for other devices. The snd_soc_codec_set_pll API defines that
a clock should be available once the call returns, however, with all the
clocking controlled in set_bias_level this is not currently the case.
This patch enables pm_runtime for the wm8804, enabling both the
regulators and the oscillator when the chip resumes, and enabling the
PLL in the snd_soc_codec_set_pll call. Naturally the enabling the PLL
will also cause the chip to resume.

This change converts the driver to use DAPM to control the power for the
various blocks on the chip. As part of this change the existing controls
"TX Playback Switch" (controlled power for the SPDIF TX block) and "AIF
Playback Switch" (controlled power for the AIF block) are both removed,
as they are now redundant since the power state of those blocks is
controlled automatically by DAPM.
There are several benefits of this change, the most important of which
is this change adds support for powering down the SPDIF RX block. The RX
block will automatically assume control of the PLL on the chip when it
is receiving a signal, so leaving this enabled all the time as was
currently done in the driver can be problematic. An incoming SPDIF signal
that is not being used can completely destroy the clocking for an in use
TX signal. But this change ensures that the RX block will only be
powered when the user intends to be receiving data, thus avoiding this
issue.
Additional benefits include the chip being simpler to operate as the
power no longer needs to be manually controlled between use-cases and a
small power saving (although it is acknowledged that this is likely
unimportant in the typical use-cases for this chip).

This patch fixes some small issues on the probe error paths. Firstly,
fail probe if we can't register the regulator notifiers as this
will cause the cache to never be synchronised which will result in odd
behaviour if the regulators are controllable. Secondly, we don't need to
call regulator_bulk_disable if the enable fails, because the regulator
core will handle this clean up for us. Finally, we need to disable the
regulators if snd_soc_register_codecs fails.

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

RT286 can't do register reset. If the hardware power is still existing
in power off, rt286 will keep the register settings. So, we need to
restore the default register value in probe to make sure the cache value
is the same as the real register value.

Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

The earpiece on wm5102 is mono, thus there is no output 3R. Don't toggle
the volume update bits for this output, although worth noting that doing
so had no negative effects it is just redundant.
