Subject: [PATCH 33/69] ALSA: gus: properly handle snd_ctl_add() error

From: Kurt Manucredo <fuzzybritches0@...il.com>

snd_gus_init_control() does not properly return any possible error that
might have happened in a call to snd_ctl_add() so resolve this by
propagating the error back up the call change correctly.
