ALSA: hda: Add error check for snd_ctl_rename_id() in snd_hda_create_dig_out_ctls()
commit 822b7ec657e99b44b874e052d8540d8b54fe8569 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 ]
