[PATCH 5.19 097/207] drm/mediatek: Fix wrong dither settings

[Greg Kroah-Hartman]

From: Allen-KH Cheng <allen-kh.cheng@xxxxxxxxxxxx>

[ Upstream commit 87fd9294e63e8fa7532b5e65b534c3001c654ef8 ]

The width and height arguments in the cmdq packet for mtk_dither_config()
are inverted. We fix the incorrect width and height for dither settings
in mtk_dither_config().

Fixes: 73d3724745db ("drm/mediatek: Adjust to the alphabetic order for mediatek-drm")
