From 3e2bd64d243ff0f3dc08c49ff218fed42ee9d981 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 27 Sep 2013 11:52:35 +0100 Subject: [PATCH] spi/s3c64xx: Ensure runtime PM is enabled prior to registration Otherwise we may try to start transfers immediately and then fail to runtime resume the device causing us not to have clocks enabled.
