Subject: [PATCH v2 5/6] media: mediatek: vcodec: decoder: Drop max_{width,height} from mtk_vcodec_ctx
Date:   Wed,  6 Jul 2022 16:21:37 +0800
Message-Id: <20220706082138.2668163-6-wenst@chromium.org>

This partially reverts commit b018be06f3c7 ("media: mediatek: vcodec:
Read max resolution from dec_capability").

After the previous patches:

  - media: mediatek: vcodec: decoder: Fix 4K frame size enumeration
  - media: mediatek: vcodec: decoder: Skip alignment for default resolution
  - media: mediatek: vcodec: decoder: Fix resolution clamping in TRY_FMT

the max_{width,height} fields in |struct mtk_vcodec_ctx| no longer have
any real users. Remove them.

Fixes: b018be06f3c7 ("media: mediatek: vcodec: Read max resolution from dec_capability")
