Subject: [PATCH v5 12/14] media: mtk-vcodec: vdec: add media device if using stateless api
Date: Wed, 19 May 2021 23:30:09 +0900	[thread overview]
Message-ID: <20210519143011.1175546-13-acourbot@chromium.org> (raw)
In-Reply-To: <20210519143011.1175546-1-acourbot@chromium.org>

From: Yunfei Dong <yunfei.dong@mediatek.com>

The stateless API requires a media device for issuing requests. Add one
if we are being instantiated as a stateless decoder.
