From 4e657946cbf68998b51b331375a1209e90792fe4 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Fri, 18 Mar 2016 16:53:31 +0100 Subject: mfd: db8500 stop passing around platform data Except for the constant DB8500_PRCMU_FW_VERSION_OFFSET number, nothing is ever passed through the platform data and used in a driver, so we can simply stop passing it around.
