[PATCH] media: s3c-camif: Avoid inappropriate kfree()

From: Katya Orlova
Date: Thu Aug 24 2023 - 05:08:55 EST


s3c_camif_register_video_node() works with video_device structure stored
as a field of camif_vp,
so it should not be kfreed. But there is video_device_release() on error
path that do it.

Found by Linux Verification Center (linuxtesting.org) with SVACE.
