From: Jiri Slaby Date: Tue, 7 Aug 2012 19:47:51 +0000 (+0200) Subject: TTY: use tty_port_link_device X-Git-Tag: v3.7-rc1~172^2~139 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=b19e2ca77ee4becadc85341bb0c1cee454dd4fd5;p=profile%2Fivi%2Fkernel-adaptation-intel-automotive.git TTY: use tty_port_link_device So now for those drivers that can use neither tty_port_install nor tty_port_register_driver but still have tty_port available before tty_register_driver we use newly added tty_port_link_device. The rest of the drivers that still do not provide tty_struct <-> tty_port link will have to be converted to implement tty->ops->install.
