From 0b9ec151b9b45fee749d32d744d50e1b721d79b2 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Tue, 13 Feb 2024 11:38:02 -0300 Subject: [PATCH] parisc: make parisc_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 parisc_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
