From 0081e83be0ca99db7bac487156d0b3ae49d936be Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Wed, 14 Feb 2024 16:28:29 -0300 Subject: [PATCH] ALSA: seq: make snd_seq_bus_type const Since commit d492cc2573a0 ("driver core: device.h: make struct bus_type a const *"), the driver core can properly handle constant struct bus_type, move the snd_seq_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
