Subject: drivers/usb/serial/ti_usb_3410_5052.c: ti_usb returns EIO when reopening the device
From: Christoph Mair <christoph.mair@gmail.com>

Fix regression introduced by 4a90f09b20f4622dcbff1f0e1e6bae1704f8ad8c
("tty: usb-serial krefs").

The driver works as expected until you close the device and try to reopen
it.  All you get from now on, is an I/O error.  It seems that something
isn't released correctly, because the refcount of the usbserial module
does not drop to zero, even when unloading all dependent drivers.
