From: Ricardo B. Marliere Date: Tue, 13 Feb 2024 14:44:40 +0000 (-0300) Subject: gpu: host1x: bus: make host1x_bus_type const X-Git-Tag: v6.9-rc1~26^2~23^2~17 X-Git-Url: https://git.kernel.dk/?a=commitdiff_plain;h=5d012e512db155ae01d01a0e51d198e0bac5bd5a;p=linux-2.6-block.git 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.
