From 78cb1f1d19b600ed288ed7ad1fd7b9378302cbc5 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sat, 3 Feb 2024 15:25:03 -0300 Subject: drm: display: make dp_aux_bus_type const Now that the driver core can properly handle constant struct bus_type, move the dp_aux_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
