I don't know if any recent ALSA changes took away the controlC nodes,
but your sound/core/sound.c::alsa_sound_init() should have a line in it
that looks like:
	class_simple_device_add(sound_class, MKDEV(major, controlnum<<5), NULL, "controlC%d", controlnum);
and that should always get called (make sure you took the stupid 
#ifdef CONFIG_DEVFS around that for loop.)

I'm guessing you didn't merge quite right :)
