ALSA: riptide: Remove always NULL parameter
snd_riptide_pcm() takes a pointer to a pointer of a PCM where if this parameter is provided the newly allocated PCM 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>
