Sorry for missing the Signed-off thing (was there in original one I had sent).
===========================================================

   Removing __init from check_platform_magic since it is called by
xen_unplug_emulated_devices in non-init contexts (It probably gets inlined
because of -finline-functions-called-once, removing __init is more to avoid
mismatch being reported).
