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.
