From 2c3a52363271526544afe9040661b26543655e65 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Mon, 8 Feb 2016 11:13:29 +0100 Subject: [PATCH] staging:iio:ad7606: Consolidate PM ops Both the SPI and platform device driver for the ad7606 use the same set of PM ops. Consolidate them in the common part of the driver.
