patch "USB: mos7720: delete parport" added to usb-linus

This is a note to let you know that I've just added the patch titled

USB: mos7720: delete parport

to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-linus branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the next -rc kernel release.

If you have any questions about this process, please let me know.

Subject: USB: mos7720: delete parport

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.
