-Subject: USB Serial: fix use-after-free bug in usb-serial core
-
-This fixes a use-after-free bug in the usb-serial core.  It is simple to
-trigger this (open a usb-serial port, then yank the device out before
-closing the port.)  Thanks to Stefan Seyfried <seife@suse.de> for
-reporting this, and to the slab debugging code which enabled it to be
-tracked down.
