[PATCH v2] media: mediatek: vcodec: using encoder device to alloc/free encoder memory
From: Yunfei Dong
Date: Tue Oct 10 2023 - 08:20:25 EST
Need to use encoder device to allocate/free encoder memory when calling
mtk_vcodec_mem_alloc/mtk_vcodec_mem_free, or leading to below crash log
when test encoder with decoder device.
