4.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wei Yongjun <weiyongj...@huawei.com>
commit bdf6f135973acb409b3ec5a6214fb597670a0bc0 upstream.
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")
