[PATCH] drm/edid: Simplify min_pixel_clock_rate calculation
Posted by Jonathan Cavitt 1 month, 2 weeks ago
In calculate_ovt_min_htotal, we compute min_pixel_clock_rate as
max_vrate * min_htotal * min_vtotal.  However, we already calculated the
value of max_vrate * min_vtotal as min_line_rate.  So, just use that as
part of the calculation.
