commits 89ce13b, b81d80d, ec4d0dc, 91256e2 and 8022a6d -
e29f558 (no idea why gitorious shows those mixed with SGX
stuff, on my local tree it is contiguous patch series)

didn't test against the current upstream, but I see no
reason why those should not apply, build and run.

The patch looks ok. It does not cleanup the cmt-speech driver
for mainline usage, but it should work. Before adding this
driver to the mainline kernel there should be open source
userspace support anyway.

Btw. I am aware that this would break existing pulse audio
stuff, but wouldn't it make sense to export a V4L2 device
instead of the custom /dev/cmt_speech ABI?

It is not good idea to break existing applications even if they 
are closed... And there are some open source meego/nemo 
pulseaudio modules which using cmt speech (but audio quality is 
worse).

Anyway what is /dev/cmt_speech doing? If it exports gsm voice 
call data, should not it have alsa snd interface?

V4L2 interface is not for video/camera/capture/tv cards?
