From 565206aaa6528b30df9294e9aafac429e4bc94eb Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 12 Feb 2024 17:05:00 -0300 Subject: powerpc: vio: make vio_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 vio_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
