Subject: media: verisilicon: Fix auxiliary buffer allocation size
Author: Benjamin Gaignard <benjamin.gaign...@collabora.com>
Date: Thu Mar 28 10:34:39 2024 +0100
Use v4l2_av1_tile_info->tile_cols to get the number of columns
in the frame and make auxiliary buffer memory size computation
more accurate.
