From 2e124b4a390ca85325fae75764bef92f0547fa25 Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Thu, 3 Jan 2013 15:53:06 +0100 Subject: TTY: switch tty_flip_buffer_push Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty in many call sites. Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.
