Subject: [PATCH v3 08/13] media: tegra-video: Add support for V4L2_EVENT_SOURCE_CHANGE
Date: Thu, 3 Dec 2020 10:59:57 -0800 [thread overview]
Message-ID: <1607022002-26575-9-git-send-email-skomatineni@nvidia.com> (raw)
In-Reply-To: <1607022002-26575-1-git-send-email-skomatineni@nvidia.com>
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.
