Oh yeah, I didn't see that.  So returning any negative number is broken.

So I don't understand the philosophy here.  Are we going to propagate errors
during read operations, or not?  It seems that sometimes ASoC does, and
sometimes it doesn't, and sometimes it doesn't even know what it wants (e.g. the
snd_soc_X_X_read functions).
