Subject: [PATCH] media: controls: Add VP8 stateless type initialization
Date: Mon, 23 Nov 2020 12:00:19 -0300 [thread overview]
Message-ID: <20201123150019.83470-1-ezequiel@collabora.com> (raw)
The VP8_FRAME_HEADER control type is validated, so it
needs a corresponding initialization to produce default
legal values.
For now, only add the minimum required initialization
to satisfy current validation.
