Hm, this should have been fixed by the later commit:
  commit 2b39535b9e54888649923beaab443af212b6c0fd
  Author: Jarkko Nikula <jhnikula at gmail.com>
  Date:   Fri May 20 15:47:40 2011 +0300

    ASoC: core: Don't set "(null)" as a driver name

Could you check whether the segfault occurs at this point?
It's possible that another bug was introduced after it, of course.
