From 10fdfd13a35994ac1dcc3003d4046cb1955e66a8 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sun, 4 Feb 2024 11:40:16 -0300 Subject: [PATCH] platform: x86: wmi: make wmi_bus_type const MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Now that the driver core can properly handle constant struct bus_type, move the wmi_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
