From 9e98966c7bb94355689478bc84cc3e0c190f977e Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 22 Jul 2008 11:18:03 +0100 Subject: tty: rework break handling Some hardware needs to do break handling itself and may have partial support only. Make break_ctl return an error code. Add a tty driver flag so you can indicate driver hardware side break support.
