From 2d7c957e2ec0aebdd595a32b884a51270d34d28d Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 15 Sep 2011 15:39:23 +0300 Subject: [PATCH] MFD: twl6040: Remove global pointer for platform_device There is no need to keep global pointer for the platform device, since it is only used for dev_* prints, and the device pointer available within the twl6040 structure.
