Subject: [PATCH] bus: sunxi-rsb: make sunxi_rsb_bus const
Date: Sun, 04 Feb 2024 12:56:44 -0300 [thread overview]
Message-ID: <20240204-bus_cleanup-bus-v1-1-bda309c4b829@marliere.net> (raw)
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.
