Subject: media: tegra-video: Add support for V4L2_EVENT_SOURCE_CHANGE
Author:  Sowjanya Komatineni <[email protected]>
Date:    Fri Dec 11 18:02:37 2020 +0100

Current implementation uses v4l2_ctrl_subscribe_event() and this
does not handle V4L2_EVENT_SOURCE_CHANGE.

So, update driver to handle V4L2_EVENT_SOURCE_CHANGE.
