    Driver core: warn when userspace writes to the uevent file in a 
non-supported way
    In the future we will allow the uevent type to be written to the uevent
    file to trigger the different types of uevents.  But for now, as we only
    support the ADD event, warn if userspace tries to write anything else to
    this file.
