Dear Mark
I have question about snd_soc_8_8_write
----------------------------- static int snd_soc_8_8_write(struct snd_soc_codec *codec, unsigned int reg, unsigned int value) { u8 *cache = codec->reg_cache; u8 data[2];
BUG_ON(codec->volatile_register);
data[0] = reg & 0xff; data[1] = value & 0xff;
if (reg < codec->reg_cache_size) cache[reg] = value;
if (codec->hw_write(codec->control_data, data, 2) == 2) return 0; else return -EIO; } -----------------------------
I wounder this behavior.
if reg >= codec->reg_cache_size, this functions will call hw_write though cache[xx] ignore it.
And even though if reg < codec->reg_cache_size, if hw_write return error, cache[xx] value was still changed.
This is correct behavior ? Or are there any reason ?
