Subject: media: cec: make cec_bus_type const
Author: Ricardo B. Marliere <rica...@marliere.net>
Date: Sat Feb 3 12:31:26 2024 -0300
Now that the driver core can properly handle constant struct bus_type,
move the cec_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
