Subject: [PATCH] rpmsg: core: make rpmsg_bus const
Date: Sun, 04 Feb 2024 17:32:05 -0300	[thread overview]
Message-ID: <20240204-bus_cleanup-rpmsg-v1-1-1703508c23b7@marliere.net> (raw)

Now that the driver core can properly handle constant struct bus_type,
move the rpmsg_bus variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
