ALSA: gus: Remove always NULL parameters
snd_gf1_pcm_new() and snd_gf1_rawmidi_new() take a pointer to a pointer of a PCM/MIDI where if this parameter is provided the newly allocated object is stored. All callers pass NULL though, so remove the parameter. This makes the code a bit cleaner and shorter. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Takashi Iwai <tiwai@suse.de>
