-- cgit v1.2.3 From 3c1534c7ecffeb4330bba4c55d17f301528195b6 Mon Sep 17 00:00:00 2001 From: Lee Jones Date: Fri, 27 Jul 2012 13:38:50 +0100 Subject: mfd: Ensure AB8500 platform data is passed through db8500-prcmu to MFD Core When booting via platform code the AB8500 platform data is now passed in though the DB8500. However, if pdata_size is not set it will not be subsequently passed onto subordinate devices. This patch correctly populates pdata_size.
