[PATCH v2] media: mtk-vcodec: remove unneeded proxy functions

Alexandre Courbot acourbot at chromium.org
Fri Jun 14 00:56:40 PDT 2019


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.
