Subject: [PATCH 26/40] ab8500-charger: Add UsbLineCtrl2 reference
Date: Fri, 15 Feb 2013 12:44:56 +0000	[thread overview]
Message-ID: <1360932310-30065-27-git-send-email-lee.jones@linaro.org> (raw)
In-Reply-To: <1360932310-30065-1-git-send-email-lee.jones@linaro.org>

From: Marcus Cooper <marcus.xm.cooper@stericsson.com>

When the state of USB Charge detection is changed then the calls
use a define for another register in other bank. This change
creates a new define for the correct register and removes the
magic numbers that are present.
