Subject[098/136] usb-serial: rename subroutines
2.6.31-stable review patch.  If anyone has any objections, please let us know.

------------------
From: Alan Stern <stern@rowland.harvard.edu>
commit 74556123e034c8337b69a3ebac2f3a5fc0a97032 upstream.

This patch (as1289) renames serial_do_down() to serial_down() and
serial_do_free() to serial_release(). It also adds a missing call to
tty_shutdown() in serial_release().
