ALSA: hda - Fix error check from snd_hda_get_conn_index() in patch_cirrus.c
snd_hda_get_conn_index() returns a negative value while the current code stores it in an unsigned int. It must be stored in a signed integer. Reported-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Takashi Iwai <tiwai@suse.de>
