If aic3x_read failed , val is used uninitialized.
Fix it by initializing val to 0.
This patch fixes below compile warning:

The WM8737 is a low power, flexible stereo ADC designed for portable
applications. This driver supports most of the functionality of the
WM8737, though some features such as the ALC are not yet implemented.

Commit ce6120c require that soc-dapm.h cannot be included before soc.h but
these two drivers were not checked. Fix them by including only soc.h as it
includes soc-dapm.h.

Allow the application to choose if the ADC data presented on the left
and right channels is sourced from the internal left or right channel.
This allows a mono recording to be presented as stereo on the external
bus.

We allocated memory for wm8962 in wm8962_i2c_probe,
and will free the memory in either wm8962_i2c_probe error path
or wm8962_i2c_remove.
Thus we should not call kfree(wm8962) in wm8962_probe, otherwise
we have double free of wm8962.

Ensure that whatever ran before us leaves the WM835x with a sane default
audio interface configuration as we do not override the companding,
loopback or tristate settings and do not reset the chip at startup (as it
is a PMIC).

The WM8350 driver was using some custom constants to interpret the direction
of the MCLK signal which had the opposite values to those used as standard
by the ASoC core, causing confusion in machine drivers such as the 1133-EV1
board.

There are no known problems with current power-up sequence which first sets
the /shutdown pin high and then enables the supply. However, swap the order
so that the device is kept in shutdown/reset mode during the supply voltage
transition since slowly rising voltages can usually cause problems if the
device is not kept in reset.

Based on discussion the dapm_pop_time in debugsfs should be per card rather
than per device. Single pop time value for entire card is cleaner when the
DAPM sequencing is extended to cross-device paths.

->

The member reg_cache is not used at all and therefore it should be
removed. This member was usually needed for older versions of ASoC
that did not handle caching automatically and had to be done in the
driver itself.

Ensure that the system does not suspend while we process a WM8962 jack
event by using pm_wakeup_event() to block the suspend while we're waiting
for the jack to settle. Use a slightly longer timeout than the jack waits
to allow for other stuff to take over and delays in scheduling.
