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);
