From fbd5f5008fab2203fa21e82579b9b48a7256b8fd Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sun, 3 Mar 2024 15:05:42 -0800 Subject: [PATCH] Input: serio - make serio_bus const Now that the driver core can properly handle constant struct bus_type, move the serio_bus variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
