Subject: [PATCH] media: am437x-vpfe: embed video_device struct in vpfe_device
From: "Lad, Prabhakar" <prabhakar.csengg@...il.com>
Embed video_device struct (video_dev) in vpfe_device and
Unregister path doesn't need to free the video_device
structure, hence, change the video_device.release callback
point to video_device_release_empty.
