you have an extra space between * and audio_setting. Please remove that.

Now this is something I don't like at all. It is copied code from the
modem plugin.
The initial discussion was that we need to configure XDRV only once
during init and never have to touch it again. That seems to be not true
anymore. So what is the deal here?
Also if this is required, we might need to figure out a complete
different way of handling this. We can't have this in two places since
that means a full disconnect. Maybe putting this into the audio settings
atom might be better. However before we can do anything, I have to
understand the semantics behind XDRV, normal voice calls and TTY calls.

What is this ctm_set_data doing here. It seems wrong.

This return is a bit out of order.

Don't bother with the remove here. We have not been doing that. So just
registering in success case is enough.

We wanna be consistent, so pleace do ifx_ctm_init(void) here.

Same here. And for extra bonus points, I accept patches that fixes this
inside the whole oFono tree ;)
It is coding style rule M15 now.
