Subject: [PATCH -next] pinctrl: samsung: Fix return value check in samsung_pinctrl_get_soc_data()
Date: Wed, 25 Jan 2017 14:03:21 +0000	[thread overview]
Message-ID: <20170125140321.23911-1-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

In case of error, the function devm_ioremap() returns NULL pointer
not ERR_PTR(). The IS_ERR() test in the return value check should
be replaced with NULL test.

Fixes: 8b1bd11c1f8f ("pinctrl: samsung: Add the support the multiple
IORESOURCE_MEM for one pin-bank")
