[Intel-gfx] [PATCH v3 6/6] drm/i915: Have pfit calculations return an error code
Ville Syrjala

Wed Apr 22 16:19:17 UTC 2020
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Change intel_{gmch,pch}_panel_fitting() to return a normal
error vs. success int. We'll need this later to validate that
the margin properties aren't misconfigured.
