From 42c4c8fdbd1a71970d2a7e71d682b6beeb9f92b1 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sat, 3 Feb 2024 11:57:59 -0300 Subject: [PATCH] s390/cio: make css_bus_type const Now that the driver core can properly handle constant struct bus_type, move the css_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
