 When trying to use the GTA02 to capture PCM data, the stable-tracking
 kernel oopses.

 The following steps can be used to reproduce this:

 $ wget http://wildsau.enemy.org/~moko/voice-recording.state
 $ alsactl -f voice-recording.state restore
 $ arecord -v -f cd -c 2 foo.wav
 Segmentation fault

 I will attach the kernel oops

Comment(by laforge):

 there seem to be actually two independent problems

 1) the fact that there are no matching rates " WM8753 HiFi <-> s3c24xx-i2s
 No matching rates"

 2) the fact that this causes a kernel oops in the
 neo1973_gta02_hifi_hw_free() function.  This is caused by
 dai_ops.set_pll() == NULL, which in turn seems to be caused by the fact
 that snd_pcm_open_substream() is not finished (due to the 'no matching
 rate' bug above) and calls snd_pcm_release_substream() for a not fully
 opened substream.

Comment(by erl):

 I think this is a dupe of bug #2073.

 It would be great if someone could raise the priority of this bug. It
 would be useful to debug microphone problems, hack VoIP, speech
 recognition and general audio recording stuff.

Comment(by andy):

 else will.
