    USB: mos7720: delete parport · 30f07618

    commit dcb21ad4 upstream.
    
    parport subsystem has introduced parport_del_port() to delete a port
    when it is going away. Without parport_del_port() the registered port
    will not be unregistered.
    To reproduce and verify the error:
    Command to be used is : ls /sys/bus/parport/devices
    1) without the device attached there is no output as there is no
    registered parport.
    2) Attach the device, and the command will show "parport0".
    3) Remove the device and the command still shows "parport0".
    4) Attach the device again and we get "parport1".
    
    With the patch applied:
    1) without the device attached there is no output as there is no
    registered parport.
    2) Attach the device, and the command will show "parport0".
    3) Remove the device and there is no output as "parport0" is now
    removed.
    4) Attach device again to get "parport0" again.
