Subject: [PATCH] media: verisilicon: Fix auxiliary buffers allocation size
Date: Thu, 28 Mar 2024 10:34:39 +0100	[thread overview]
Message-ID: <20240328093439.18712-2-benjamin.gaignard@collabora.com> (raw)
In-Reply-To: <20240328093439.18712-1-benjamin.gaignard@collabora.com>

Use v4l2_av1_tile_info->tile_cols to know the number of colons
in the frame. This made auxiliary buffers meory size computation
more accurate.
