From cb1c1224193e648b4108dd06ebb7cc86b5c514ad Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Mon, 12 Feb 2024 08:41:01 -0300 Subject: dio: make dio_bus_type const Now that the driver core can properly handle constant struct bus_type, move the dio_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
