Subject: [PATCH 3/5] console: Set baudrate during registration
Date: Tue, 17 Nov 2015 12:10:49 +0100	[thread overview]
Message-ID: <1447758651-26575-4-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1447758651-26575-1-git-send-email-s.hauer@pengutronix.de>

This makes sure that the cdev->baudrate field is always consistent with
the hardware state.
