From 121ea573aeb7e9b1d79effa8ef7970031aebda12 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Wed, 6 Apr 2011 11:41:03 +0200 Subject: w1: Use device platform_data to retrieve ds1wm platform bits With the addition of the platform device mfd_cell pointer, we can now cleanly pass the sub device drivers platform data pointers through the regular device platform_data one, and get rid of mfd_get_data().
