Subject: platform/wmi: Make wmi_bus_class const
X-Git-Tag: v7.2-rc1~61^2~17
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=b79ad5e8ba5cfda93a83e0cf71d4743829cc9f83;p=thirdparty%2Fkernel%2Flinux.git

platform/wmi: Make wmi_bus_class const

The functions class_register()/_unregister() and device_create()
both support taking a const pointer to the class struct. Use this
to mark wmi_bus_class as const so that it can be placed into
read-only memory for better security.
