From 592190b598c3a9fdf98c5fc649e5f6da6e8e7941 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sun, 11 Feb 2024 12:37:11 -0300 Subject: 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.
