[BUG] NULL pointer dereference in patch_sigmatel.c

["Ozan Çağlayan" <ozan@pardus.org.tr>]

Hi,

One of our users is having a NULL ptr dereference upon loading the
snd_hda_intel module with 20090624's snapshot. There's only one commit
after that date in patch_sigmatel.c so I didn't tell him to try with the
latest snapshot but if you think that the bug may be related to another
part of the ALSA codebase, I can make him try the latest snapshot.

I'm attaching the alsa-info output on a working system with 1.0.18a. The
kernel version in subject is 2.6.25.20.

Thanks,
Ozan
