X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bbc7e4cc21a43d7991a5c9a163d2990daddc8411;p=linux.git

net: bridge: constify the struct device_type usage

Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the br_type
variable to be a constant structure as well, placing it into read-only
memory which can not be modified at runtime.
