From 5d012e512db155ae01d01a0e51d198e0bac5bd5a Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Tue, 13 Feb 2024 11:44:40 -0300 Subject: gpu: host1x: bus: make host1x_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 host1x_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
