Eek, I can't look away...

You do this a bunch:
	if (dev->visorchannel) {
		visorchannel_destroy(dev->visorchannel);

yet the first thing that visorchannel_destroy() does is check for null.
So, no need to test this twice, right, only do so in the function, that
will make your code flow a lot "smoother" where ever you are calling
this.

Ok, I'll stop now, gotta go find some dinner...
