From cc28e17100a6b051ef966de81bb2d4a97b2a6645 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 13 Apr 2012 10:15:49 +0200 Subject: ab8500_charger: 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.
