Subject: [PATCH -next v2] input: touchscreen: mxs-lradc: Fix return value check in mxs_lradc_ts_probe()
Date: Thu, 27 Apr 2017 15:13:52 +0000	[thread overview]
Message-ID: <20170427151352.23463-1-weiyj.lk@gmail.com> (raw)
In-Reply-To: <20170425062646.26043-1-weiyj.lk@gmail.com>

From: Wei Yongjun <weiyongjun1@huawei.com>

In case of error, the function devm_ioremap() returns NULL pointer not
ERR_PTR(). Use devm_ioremap_resource() instead of devm_ioremap().

Signed-off-by: Wei Yongjun <weiyongjun1@huawei.com>

v1 -> v2: use devm_ioremap_resource()
