From 2aa237f4a1a72813f9684a0ce6e48288e75de479 Mon Sep 17 00:00:00 2001 From: Axel Lin Date: Wed, 26 Feb 2014 09:47:55 +0800 Subject: spi: coldfire-qspi: Enable clock before calling spi_master_resume This ensures clock has been enabled before calling spi_master_resume(). while at it, also add checking return value of spi_master_suspend and spi_master_resume because they may fail.
