[PATCH] ALSA: hda-intel - Fix detection of audio codec on Toshiba A100
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).
