Subject: [PATCH] mei: bus: constify the struct mei_cl_bus_type usage
Date: Tue, 23 Apr 2024 10:41:33 +0800 [thread overview]
Message-ID: <20240423024133.1890455-1-chentao@kylinos.cn> (raw)
Now that the driver core can properly handle constant struct bus_type,
move the mei_cl_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
