From 24e041e1e48d06f25a12caaf73728a4ec2e511fe Mon Sep 17 00:00:00 2001 From: Kunwu Chan Date: Fri, 23 Aug 2024 15:55:44 +0800 Subject: platform: Make platform_bus_type constant 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 platform_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
