From 0daf87e7b47e05d0c9ccab648d5e45eaddb547f8 Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Sun, 4 Feb 2024 12:56:44 -0300 Subject: bus: sunxi-rsb: make sunxi_rsb_bus const Now that the driver core can properly handle constant struct bus_type, move the sunxi_rsb_bus variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
