The variable idx is being initialized with a value that is never
read and it is being updated later with a new value. The
initialization is redundant and can be removed.

Split regmap_config.use_single_rw into use_single_read and
use_single_write. This change enables drivers of devices which only
support bulk operations in one direction to use the regmap_bulk_*()
functions for both directions and have their bulk operation split into
single operations only when necessary.
Update all struct regmap_config instances where use_single_rw==true to
instead set both use_single_read and use_single_write. No attempt was
made to evaluate whether it is possible to set only one of
use_single_read or use_single_write.

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.

We will set some volatile registers in jack detection function. But
those volatile registers will be clear in rt5665_calibrate function
because we set cache bypass and reset codec in rt5665_calibrate function.

before starting jack detection.

With gcc 4.1.2:
sound/soc/codecs/rt5665.c: In function ‘rt5665_i2s_pin_event’:
sound/soc/codecs/rt5665.c:2610: warning: ‘mask1’ may be used uninitialized in this function
sound/soc/codecs/rt5665.c:2610: warning: ‘val2’ may be used uninitialized in this function
sound/soc/codecs/rt5665.c:2610: warning: ‘val1’ may be used uninitialized in this function
The first one is currently a false positive, as rt5665_i2s_pin_event()
is never called with snd_soc_dapm_widget.shift set to a value not
handled by the switch() statement. But that may change, so
preinitialize mask1 to fix this, like is already done for mask2.
The last two are false-positives, the compiler is just not smart enough
to notice the mask and val variables are always used together.
