[PATCH 2/4] drm/amd/display: dcn20: Use min()/max() helper macros

From: Deepak R Varma
Date: Sat Jan 14 2023 - 16:20:59 EST


Use the standard min() / max() helper macros instead of direct variable
comparison using if/else blocks or ternary operator. Change identified
using minmax.cocci Coccinelle semantic patch.
