3bb4852d59 ASoC: codecs: wcd934x: add a sanity check in set channel map 
set channel map can be passed with a channel maps, however if
the number of channels that are passed are more than the actual
supported channels then we would be accessing array out of bounds.

So add a sanity check to validate these numbers!

eaf2767cad ASoC: codecs: wcd*: rename to snd_soc_component_read() 
We need to use snd_soc_component_read()
instead of     snd_soc_component_read32()

This patch renames _read32() to _read()

2 warnings generated.

Arrays that are in the middle of a struct are never NULL so they don't
need a check like this.

a61f3b4f47 ASoC: wcd934x: add support to wcd9340/wcd9341 codec 
Qualcomm WCD9340/WCD9341 Codec is a standalone Hi-Fi audio codec IC,
It supports both I2S/I2C and SLIMbus audio interfaces.
On slimbus interface it supports two data lanes; 16 Tx ports
and 8 Rx ports. It has Five DACs and seven dedicated interpolators,
Seven (six audio ADCs, and one VBAT ADC), Multibutton headset
control (MBHC), Active noise cancellation, Sidetone paths,
MAD (mic activity detection) and codec processing engine.
It supports Class-H differential earpiece out and stereo single
ended headphones out.
This codec also has integrated SoundWire controller.

This patchset adds very basic support for playback and capture
via the interpolators and ADC respectively.
