ALSA: usb-audio: Fix comment
Explained by Takashi in <s5hfwbtmz0q.wl%tiwai@suse.de> > The reason is because get_min_max*() isn't called in the place you > created these controls, and get_min_max() would be called only for > integer volumes later even if uninitialized. A short cut for booleans. Signed-off-by: Mark Hills <mark@pogo.org.uk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
