[PATCH v2] media: aspeed-video: Fix memory leaks in aspeed_video_probe

From: Navid Emamdoost
Date: Mon Oct 28 2019 - 12:58:43 EST

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")
