[PATCH -next] drm/nouveau/secboot/gm20b: fix the error return code in gm20b_secboot_tegra_read_wpr() - dri-devel - freedesktop.org experimental mailing list

25 Apr 2017

From: Wei Yongjun weiyongjun1@huawei.com
The error return code PTR_ERR(mc) is always 0 since mc is
equal to 0 in this error handling case.
