-stable review patch. If anyone has any objections, please let us know.
---------------------
From: Takashi Iwai <[email protected]>
Some boards have the audio codec on slot #3 while the modem codec
on slot #0. The driver should continue to probe the slots when
no audio codec is found.
This fixes the problem of no device on Toshiba A100 (and some other
ATI SB450 devices).
