ASoC: add snd_soc_component_read32
Current codec drivers are using snd_soc_read(). It will be replaced
into snd_soc_component_read(), but these 2 are using different style.
For example, it will be
- val = snd_soc_read(xxx, reg);
+ ret = snd_soc_component_read(xxx, reg, &val);
+ if (ret < 0) {
+ ...
+ }
To more smooth replace, let's add snd_soc_component_read32
which is copied from snd_soc_read()
- val = snd_soc_read(xxx, reg);
+ val = snd_soc_component_read32(xxx, reg);
