From: Zhen Lei Date: Tue, 15 Oct 2024 01:40:53 +0000 (+0800) Subject: media: nuvoton: Fix an error check in npcm_video_ece_init() X-Git-Tag: v6.12.14~98 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bdd823b9d068284e1d998b962cfef29236365df3;p=thirdparty%2Fkernel%2Fstable.git media: nuvoton: Fix an error check in npcm_video_ece_init() commit c4b7779abc6633677e6edb79e2809f4f61fde157 upstream. When function of_find_device_by_node() fails, it returns NULL instead of an error code. So the corresponding error check logic should be modified to check whether the return value is NULL and set the error code to be returned as -ENODEV.
