From: Ricardo B. Marliere Date: Sun, 11 Feb 2024 15:37:11 +0000 (-0300) Subject: ACPI: bus: make acpi_bus_type const X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=592190b598c3a9fdf98c5fc649e5f6da6e8e7941;p=linux.git ACPI: bus: make acpi_bus_type const Now that the driver core can properly handle constant struct bus_type, move the acpi_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
