Subject: [PATCH 6/8] serial: imx: bit &/| confusion
Date: Wed, 20 Jan 2010 15:50:01 -0800	[thread overview]
Message-ID: <1264031403-32239-6-git-send-email-gregkh@suse.de> (raw)
In-Reply-To: <20100120234759.GC32068@kroah.com>

From: Roel Kluin <roel.kluin@gmail.com>

Since UCR1_UARTEN is defined 1, the port was always treated as enabled.
