Subject: media: bdisp: fix memleak on release
Author:  Johan Hovold 
Date:Thu Oct 10 10:13:31 2019 -0300

If a process is interrupted while accessing the video device and the
device lock is contended, release() could return early and fail to free
related resources.

Note that the return value of the v4l2 release file operation is
ignored.

framework")
