Subject: [PATCH v2] media: aspeed-video: Fix memory leaks in aspeed_video_probe
Date: Mon, 28 Oct 2019 11:58:26 -0500 [thread overview]
Message-ID: <20191028165827.24949-1-navid.emamdoost@gmail.com> (raw)
In-Reply-To: <d9c04318-586a-bfc2-fce6-6218c6bab1d6@linux.intel.com>
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.
Fixes: d2b4387f3bdf ("media: platform: Add Aspeed Video Engine driver")
