From: Benjamin Gaignard <benjamin.gaignard@collabora.com>

[ Upstream commit d7f4149df818463c1d7094b35db6ebd79f46c7bd ]

Use pps->column_width_minus1[j] + 1 as value for the tile info buffer
instead of pps->column_width_minus1[j + 1].
The patch fixes DBLK_E_VIXS_2, DBLK_F_VIXS_2, DBLK_G_VIXS_2,
SAO_B_MediaTek_5, TILES_A_Cisco_2 and TILES_B_Cisco_1 tests in fluster.

Fixes: cb5dd5a0fa51 ("media: hantro: Introduce G2/HEVC decoder")
