Mark Johnston 5c2b216a1c mixer: Fix default_unit switching with mixers that have no devices ... Apparently it's possible for a mixer to have no devices: $ mixer -f /dev/mixer2 pcm2:mixer: <USB audio> at ? kld snd_uaudio (rec) $ If this is the default sound device, an attempt to change the default unit using mixer -d fails with a segfault because mod_dunit is called with a NULL device pointer, which is dereferenced to get the parent mixer. ctl_dunit seems to be a dummy, i.e., we don't actually need it and can simply pass the mixer to mod_dunit() directly. This patch removes that structure and associated indirection to fix the crash.
