Subject: USB: mos7720: delete parport

From: Sudip Mukherjee <[email protected]>

commit dcb21ad4385731b7fc3ef39d255685f2f63c8c5d 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.
