Subject: net: wwan: core: constify the struct device_type usage
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7eccf41b3bacb97092bffb23853529277c20e46a;p=linux.git

net: wwan: core: 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 wwan_type
variable to be a constant structure as well, placing it into read-only
memory which can not be modified at runtime.
