From b7a2a1c0b67283442a06fcc679cba0683914f794 Mon Sep 17 00:00:00 2001 From: Heiner Kallweit Date: Sun, 27 Sep 2015 18:47:35 +0200 Subject: [PATCH] spi: ath79: simplify iomem resource mapping Simplify the code by switching from devm_ioremap to devm_ioremap_resource. Checking the result of platform_get_resource is not needed as devm_ioremap_resource checks the provided resource argument for NULL.
