From 5a78401623740c892868d5929b33f5cda8fe819e Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 18 Mar 2014 14:11:26 +0100 Subject: mfd: sec-core: Fix uninitialized 'regmap_rtc' on S2MPA01 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Initialize the 'regmap_rtc' on S2MPA01 to some sane value. Sane at least for S5M87X chipsets, not S2MPS/S2MPA but it won't be used because rtc-s5m driver does not support S2MPA01.
