The snd_soc_dapm_xxxx_pin all require the dapm_mutex to be held when
they are called as they edit the dirty list, however very few of the
callers do so.
This patch adds unlocked versions of all the functions replacing the
existing implementations with one that holds the lock internally. We
also fix up the places where the lock was actually held on the caller
side.

When system on the suspend state, Some SoC can't get gpio interrupt.
After system resume, need send extcon uevent to userspace.

This patch supports Maxim MAX14577 MUIC(Micro USB Interface Controller)
device by using EXTCON subsystem to handle various external connectors.
The max14577 device uses regmap method for i2c communication and
supports irq domain.

extcon: arizona: Add support for headphone detection on wm5110 rev D2014-01-07T02:54:28ZCharles Keepaxckeepax@opensource.wolfsonmicro.com2013-11-14T16:18:25Zurn:sha1:77438610ffd93462348346430d17470cd3ce7bbc
wm5110 rev D is the first chip to use headphone detection IP 2, specify
such and make a small correction as the impedance value is actually read
in 0.5 ohm increments now.

No point in revisiting ranges the detection will be no more accurate
the second time simply report that the resistance is right on the
range boundry.

The microphone detection code is run as delayed work to provide
additional debounce, it is possible that the jack could have been
removed by the time we process the microphone detection. Turn this
case into a no op.

Always cross check with the ID state and the source of interrupt.
Also add a case in which ID Source is ID_GND but LATCH state is set
wrongly. This uses the previous Link stat to determine the new state.
