ALSA: hda: Add error check for snd_ctl_rename_id() in snd_hda_create_dig_out_ctls()

Browse source

commit 822b7ec657 upstream.

Check the return value of snd_ctl_rename_id() in
snd_hda_create_dig_out_ctls(). Ensure that failures
are properly handled.

[ Note: the error cannot happen practically because the only error
  condition in snd_ctl_rename_id() is the missing ID, but this is a
  rename, hence it must be present.  But for the code consistency,
  it's safer to have always the proper return check -- tiwai ]
