From 9e31364fc3272073ec8c5fac18a3e01d4f013418 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Fri, 31 Jul 2015 16:59:52 -0400 Subject: [PATCH] serial: core: Remove tty port activate() and shutdown() methods serial core does not use tty_port_open() or tty_port_close(); serial core defines and extends it's own tty open() and close() methods (uart_open() and uart_close(), respectively). Remove the tty_port activate() and shutdown() initializations, and the uart_port_activate() function, which is never called. NB: uart_port_shutdown() is used by uart_close() => uart_shutdown() call chain (but not via the tty_port methods).
