3.5.7u1 -stable review patch.  If anyone has any objections, please let me know.


From: Johan Hovold <jhovold@gmail.com>

commit 3eb55cc4ed88eee3b5230f66abcdbd2a91639eda upstream.

The driver set the usb-serial port pointers to NULL on errors in attach,
effectively preventing usb-serial core from decrementing the port ref
counters and releasing the port devices and associated data.
