Takashi Iwai 3743544624 [ALSA] portman2x4 - Fix probe error 
Reported by Ingo Molnar,
when booting an allyesconfig bzImage kernel the bootup hangs in the
portman2x4 driver (on a box that does not have this hardware), at:

the reason is due to an inconsistent error return code of 1 or 2, while
snd_portman_probe only realizes negative error codes.
