[PATCH 04/12] net: vxlan: constify the struct device_type usage
Posted by Ricardo B. Marliere 1 year, 11 months ago
Since commit aed65af1cc2f ("drivers: make device_type const"), the driver
core can properly handle constant struct device_type. Move the vxlan_type
variable to be a constant structure as well, placing it into read-only
memory which can not be modified at runtime.
