From 3954b7bfc665fed878cabe57342bae34d2391478 Mon Sep 17 00:00:00 2001 From: Sebastian Andrzej Siewior Date: Thu, 19 Dec 2013 16:28:30 +0100 Subject: mfd: ti_am335x: Drop am335x_tsc_se_update() from resume path The update of the SE register in MFD doesn't look right as it has nothing to do with it. The better place to do it is in TSC driver (which is already doing it) and in the ADC driver which needs this only in the continues mode.
