Subject: [PATCH -next] drm/hisilicon/hibmc: Fix wrong pointer passed to PTR_ERR()
Date: Thu, 12 Jan 2017 15:19:21 +0000	[thread overview]
Message-ID: <20170112151921.16538-1-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1@huawei.com>

PTR_ERR should access the value just tested by IS_ERR, otherwise
the wrong error code will be returned.

Fixes: d1667b86795a ("drm/hisilicon/hibmc: Add support for frame buffer")
