From 88cddfb7bf23b06876da6c3e9f296e666d0f6332 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sat, 3 Feb 2024 16:14:50 -0300 Subject: [PATCH] serdev: make serdev_bus_type const Now that the driver core can properly handle constant struct bus_type, move the serdev_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
