From b3ea5f451e4e435b650e34142f8552002dc21297 Mon Sep 17 00:00:00 2001 From: Marcus Cooper Date: Wed, 29 Aug 2012 17:56:19 +0200 Subject: [PATCH] ab8500-charger: Add UsbLineCtrl2 reference 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.
