| |
2.6.32-longterm 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.
