From 362e9cd2f54e3c72a37ff8e3319366554e48c555 Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Sun, 12 May 2013 15:19:50 +0200 Subject: [PATCH] drivers/pwm: don't check resource with devm_ioremap_resource devm_ioremap_resource does sanity checks on the given resource. No need to duplicate this in the driver.
