Subject: [PATCH 3/5] media: mtk-vcodec: remove unneeded proxy functions
Date:   Tue,  4 Jun 2019 18:37:35 +0900
Message-Id: <20190604093737.172599-4-acourbot@chromium.org>
In-Reply-To: <20190604093737.172599-1-acourbot@chromium.org>
References: <20190604093737.172599-1-acourbot@chromium.org>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

We were getting the codec interface through a proxy function that does
not bring anything compared to just accessing the interface definition
directly, so just do that. Also make the decoder interfaces const.
