From f9b841af4c1c3c3b7ce3552ab5ee5d9c430e9c29 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 9 Oct 2015 10:39:27 +0100 Subject: [PATCH] spi: spi-coldfire-qspi: enable RuntimePM before registering to the core The core may register clients attached to this master which may use funtionality from the master. So, RuntimePM must be enabled before, otherwise this will fail.
