ALSA: usb-audio: Unify M-Audio Fast Track Ultra and Ebox-44 mixer quirks.
Merge snd_maudio_ftu_create_ctl() and snd_ebox44_create_ctl() into snd_create_std_mono_ctl(). As opposed to the ftu and ebox-44 specific functions, a TLV callback can be specified for controls created by snd_create_std_mono_ctl(). [fixed minor checkpatch.pl warnings by tiwai] Signed-off-by: Felix Homann <linuxaudio@showlabor.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
