[Intel-gfx] [PATCH 8/8] drm/i915: Have pfit calculations return an error code
Ville Syrjala

Tue Oct 22 17:55:54 UTC 2019
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.
