TTY: convert more flipping functions
Now, we start converting tty buffer functions to actually use tty_port. This will allow us to get rid of the need of tty pointer in many call sites. Only tty_port will be needed and hence no more tty_port_tty_get calls in those paths. Now 4 string flipping ones are on turn: * tty_insert_flip_string_flags * tty_insert_flip_string_fixed_flag * tty_prepare_flip_string * tty_prepare_flip_string_flags Signed-off-by: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
