snd_ctl_add() could fail, so let's check its return value and return its error code upstream upon failure.

The code change looks OK, but could you fix the indentation and avoid unneeded line breaks, as well as the missing braces for else-block?
Also, we keep "ALSA:" prefix for the subject line (except for ASoC ones). Please align with it.
