From 5f98eb393c6d7a5de3202b7ce9e4439292e952fb Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 13 Apr 2012 10:16:13 +0200 Subject: ab8500_fg: Harden platform data check If no platform data at all is supplied the driver crashes, extend the checks to be more careful so we can compile in the driver and boot also without platform data present.
