Subject: drm/sun4i: hdmi: Fix incorrect assignment in sun4i_tmds_determine_rate
Git-commit: 58faae28f64e9cb6d7f89596656db640392a1efc
Patch-mainline: v4.15-rc9
References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166
best_div is set to i which corresponds to rate halving when it should be
set to j which corresponds to the divider.
