Subject: net: netdevsim: constify the struct device_type usage
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=52042e092ba9cf9120ffe516dd03acb1d1e572b9;p=linux.git

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