From f6f0d58edfa77d18c41777740958f467de615728 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Tue, 25 Aug 2020 05:52:34 +0200 Subject: [PATCH] media: uapi: h264: Drop SLICE_PARAMS 'size' field The SLICE_PARAMS control is intended for slice-based devices. In this mode, the OUTPUT buffer contains a single slice, and so the buffer's plane payload size can be used to query the slice size. To reduce the API surface drop the size from the SLICE_PARAMS control. A follow-up change will remove other members in SLICE_PARAMS so we don't need to add padding fields here.
