ASoC: add snd_soc_component_read32 (738b49ef) · Commits · 戴 / test

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); Signed-off-by:
