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:
 Pid: 1, comm:              swapper
 EIP: 0060:[<c02f763c>] CPU: 0
 EIP is at parport_pc_read_status+0x4/0x8
  EFLAGS: 00000202    Not tainted  (2.6.23-rc9 #904)
 EAX: f7e57a7f EBX: 00000010 ECX: c2b808c0 EDX: 00000379

  [<c02faea1>] bus_for_each_drv+0x35/0x68
  [<c02fbc22>] device_attach+0x72/0x78
the reason is due to an inconsistent error return code of 1 or 2, while
snd_portman_probe only realizes negative error codes.
