Hi Mark,
I have a question regarding "Fix backport of WM8994 thermal warning" patch.
I am trying sound on Exynos4 smdk board with the latest 3.1 kernel. In
the function "wm8994_codec_probe", the kernel crashes due to null
pointer when requesting "Thermal Warning" interrupt (line# 3183 of
sound/soc/codecs/wm8994.c file). wm8994->control_data is actually NULL
at this point.
I have not debugged this much but if there is something obvious I am
missing, could you please let me know.
Thanks,
Thomas.

Do you mean the latest mainline? The thermal warning support was only
implemented for v3.1 and the line numbers only match up with mainline.

This is just a straight bug, I'll post a patch.

Yes. I was referring to the latest mainline. I incorrectly wrote 3.1 above.
