ALSA: seq: Constify struct snd_midi_op
Change the argument of snd_midi_process_event() to receive a const snd_midi_op pointer and its callers respectively. This allows further optimizations. There should be no functional changes by this patch. Link: https://lore.kernel.org/r/20200103081714.9560-30-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
