Subject: [PATCH] ASoC: samsung: s3c24xx-i2s: Fix return value check in s3c24xx_iis_dev_probe()
Date: Thu, 16 Apr 2015 20:18:02 +0800	[thread overview]
Message-ID: <1429186682-20629-1-git-send-email-weiyj_lk@163.com> (raw)

From: Wei Yongjun <yongjun_wei@trendmicro.com.cn>

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().
