From 044c566d05035af5092f65a2912a28312dada8fe Mon Sep 17 00:00:00 2001 From: "Ricardo B. Marliere" Date: Fri, 9 Feb 2024 20:27:48 -0300 Subject: [PATCH] media: bt8xx: make bttv_sub_bus_type const Now that the driver core can properly handle constant struct bus_type, move the bttv_sub_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
