From 0b1db83081599615cf7b254aebc14a2d8f6ca056 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Wed, 9 Nov 2011 21:33:50 +0100 Subject: [PATCH] TTY: serial, define uart_port_activate/shutdown This is a preparation for the next patches which will move the stuff from uart_open and uart_close/hangup here. Then we will use tty_port_* helpers.
