Subject: [PATCH 02/10] media: uapi: h264: Further clarify scaling lists order
Date: Wed, 15 Jul 2020 17:22:25 -0300	[thread overview]
Message-ID: <20200715202233.185680-3-ezequiel@collabora.com> (raw)
In-Reply-To: <20200715202233.185680-1-ezequiel@collabora.com>

Commit 0b0393d59eb4a ("media: uapi: h264: clarify
expected scaling_list_4x4/8x8 order") improved the
documentation on H264 scaling lists order.

This commit improves the documentation by clarifying
that the lists themselves are expected in matrix order.
