This doesn't seem right to me. Here, the .put function returns 0 or 1, depending on whether or not the bits were actually updated. Is that what's intended? I can't find any documentation that tells me what the return values of snd_kcontrol_put_t are supposed to be.
It's supposed to be 1 for change, 0 for no change or an error - if you look at the core functions you'll see that they generally all follow this idiom of using the return value from snd_soc_update_bits() directly.
