From ec511672b97383107d87e86921b1f0392bc1d000 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 13 Apr 2012 10:16:06 +0200 Subject: [PATCH] ab8500_btemp: 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.
