    commit 6f9193ec upstream.
    
    modprobe is not able to resolve sysfs modalias for mei devices.
    
     # cat
    /sys/class/watchdog/watchdog0/device/watchdog/watchdog0/device/modalias
    mei::05b79a6f-4628-4d7f-899d-a91514cb32ab:
     # modprobe --set-version 4.9.6-200.fc25.x86_64 -R
    mei::05b79a6f-4628-4d7f-899d-a91514cb32ab:
    modprobe: FATAL: Module mei::05b79a6f-4628-4d7f-899d-a91514cb32ab: not
    found in directory /lib/modules/4.9.6-200.fc25.x86_64

    alias mei:*:05b79a6f-4628-4d7f-899d-a91514cb32ab:*:* mei_wdt
    
    commit b26864ca ("mei: bus: add client protocol
    version to the device alias"), however sysfs modalias
    is still in formmat mei:S:uuid:*.
    
    This patch equates format of uevent and sysfs modalias so that modprobe
    is able to resolve the aliases.
    
    Fixes: commit b26864ca ("mei: bus: add client protocol version to the device alias")
