Subject: [PATCH v3] media: aspeed-video: Fix memory leaks in aspeed_video_probe
Date:   Mon, 28 Oct 2019 12:18:37 -0500
Message-Id: <20191028171838.28533-1-navid.emamdoost@gmail.com>

Precedence: bulk

In the implementation of aspeed_video_probe() the allocated memory for
video should be released if either devm_ioremap_resource()
or aspeed_video_init() or aspeed_video_setup_video() fails. Replace
kzalloc() with devm_kzalloc to avoid explicit release for video.
