Subject: [PATCH] media: tw686x: Fix memory leak in tw686x_video_init
Date: Tue, 21 Jun 2022 09:30:30 +0400 [thread overview]
Message-ID: <20220621053030.6747-1-linmq006@gmail.com> (raw)
video_device_alloc() allocates memory for vdev,
when video_register_device() fails, it doesn't release the memory and
leads to memory leak, call video_device_release() to fix this.
Fixes: 704a84ccdbf1 ("[media] media: Support Intersil/Techwell TW686x-based video capture cards")
