From d87d9b7d19f04b16c4406d3c0feeca10090e0ada Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 1 Jun 2010 22:52:53 +0200 Subject: tty: serial - fix tty referencing in set_ldisc Pass down the ldisc number so that the drivers don't have to peek into the tty object themselves. This lets us get rid of another case of back referencing port to tty which we don't want (because of races versus hangup/close).
