From c8448051a5e7fda464486eaf5a4ef0c5b6d96673 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Wed, 30 Jul 2014 08:04:12 +0800 Subject: ASoC: sirf-audio-codec: Fix return value check in sirf_audio_codec_driver_probe() In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
