From afb7a966b54600d678f57535be6e5ef3156f04f1 Mon Sep 17 00:00:00 2001 From: "Lad, Prabhakar" Date: Sun, 8 Mar 2015 11:40:53 -0300 Subject: [PATCH] [media] media: blackfin: bfin_capture: embed video_device struct in bcap_device Embed video_device struct (video_dev) in bcap_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.
