From a9bce1b03c2199e66d36cda8aac675338bc074a7 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Wed, 5 Jun 2013 16:13:47 +0200 Subject: mfd: input: iio: ti_am335x_adc: use one structure for ti_tscadc_dev The mfd driver creates platform data for the child devices and it is the ti_tscadc_dev struct. This struct is copied for the two devices. The copy of the structure makes a common lock in this structure a little less usefull. Therefore the platform data is not a pointer to the structure and the same structure is used. While doing the change I noticed that the suspend/resume code assumes the wrong pointer for ti_tscadc_dev and this has been fixed as well.
