From b70d28dfb4641a54691f2bf133f30cc74588957e Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 1 Sep 2009 11:39:40 -0400 Subject: usb-serial: rename subroutines 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().
