From 731922a5939e653ce501b7d72bfe8fbe79717abf Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Sun, 5 Jan 2020 15:47:21 +0100 Subject: ALSA: seq: More constifications Apply const prefix to the remaining sequencer code: the static tables for MIDI macros, RPN/NRPN, and some strings. Just for minor optimization and no functional changes.
