------------------------------------------------------
Subject: uml: console driver cleanups
From: Jeff Dike <[EMAIL PROTECTED]>
Console driver cleanups -
Changed an instance of foo = bar + foo to foo += bar
Removed checks of tty->stopped - I don't think the low-level
driver has any business looking at that
Removed an annoying warning
