From d75b32853d4a89a8901991f294ff24b2f8fe1da5 Mon Sep 17 00:00:00 2001 From: Wei Yongjun Date: Tue, 23 Mar 2021 12:29:03 +0100 Subject: [PATCH] media: imx-jpeg: Fix return value check in mxc_jpeg_attach_pm_domains() In case of error, the function device_link_add() returns NULL pointer not ERR_PTR(). The IS_ERR() test in the return value check should be replaced with NULL test.
