+------------------
+From: Alan Stern <stern@rowland.harvard.edu>
+
+commit 0a3c8549ea7e94d74a41096d42bc6cdf43d183bf upstream.
+
+This patch (as1244) fixes a crash in usb-serial that occurs when a
+sub-driver returns a positive value from its attach method, indicating
+that new firmware was loaded and the device will disconnect and
+reconnect. The usb-serial core then skips the step of registering the
+port devices; when the disconnect occurs, the attempt to unregister
+the ports fails dramatically.
+
+This problem shows up with Keyspan devices and it might affect others
+as well.
+
+When the attach method returns a positive value, the patch sets
+num_ports to 0. This tells usb_serial_disconnect() not to try
+unregistering any of the ports; instead they are cleaned up by
+destroy_serial().
