From aad7ebb544072bcb9335fa4eb0fbd1b85a6c495b Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 3 Jan 2020 09:16:45 +0100 Subject: 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.
