From: Heikki Krogerus Date: Wed, 16 Jan 2013 12:08:13 +0000 (+0200) Subject: serial: 8250_dma: Switch to using tty_port X-Git-Tag: v3.9-rc1~125^2~85 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=6f3fe3b1027bf50c0a0859e5c9ee93b174b95543;p=linux.git serial: 8250_dma: Switch to using tty_port The tty buffer functions are converted to using tty_port structure instead of struct tty, so we must do the same.
