Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.
Done using Coccinelle:

The gpiod API checks for NULL descriptors, so there is no need to
duplicate the check in the driver.

codec driver and component driver has duplicated callback functions,
and codec side functions are just copied to component side when
register timing. This was quick-hack, but no longer needed.
This patch moves these functions from codec driver to component driver.

The dapm field of the snd_soc_codec struct is eventually going to be
removed, in preparation for this replace all manual access to
codec->dapm.bias_level with snd_soc_codec_get_bias_level() and all
remaining access to codec->dapm with snd_soc_codec_get_dapm().

sound/soc/codecs/adau1977.c:496:5-8: WARNING: end returns can be simpified
Simplify a trivial if-return sequence. Possibly combine with a
preceding function call.

All drivers have the same line at the end of the set_bias_level callback to
update the bias_level state. Move this update into
snd_soc_dapm_force_bias_level() and remove them from the drivers.

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions)
which appeared in v3.17-rc1, the gpiod_get* functions take an additional
parameter that allows to specify direction and initial value for
output. Simplify drivers accordingly.
Also there is an *_optional variant that serves well here. The sematics
is slightly changed here by using it as error checking is more strict
now: If GPIOLIB is not enabled an error is returned instead of just
ignoring the gpio. On one hand this is bad for devices that don't "have"
the respective gpio as the driver is failing now. On the other hand
there is no means to assert that this gpio is really not needed or if
only the driver to control it is not available. The latter is a real
reason to fail and so it's defensive to fail here, too.

Negating ADAU1977_BLOCK_POWER_SAI_LDO_EN creates an unsigned long constant
with all bits set which on 64 bit architectures needs to be truncated to
an unsigned int, generating a warning. Add an explicit cast since we know
this is OK.

This patch adds support for the ADAU1977, ADAU1978 and ADAU1979 audio CODEC
devices. They are a family of 4-channel differential input audio ADC devices.
They can be connected to either a SPI or I2C bus. The driver is implemented in
three modules, one main module (adau1977.ko) which implements the device logic
and one module each for SPI (adau1977-spi.ko) and I2C (adau1977-i2c.ko) bus
access.
