Subject: [Intel-gfx] [PATCH] drm/i915: Properly flag modesets for all bigjoiner pipes
Date: Fri, 20 Nov 2020 18:01:35 +0200	[thread overview]
Message-ID: <20201120160135.29702-1-ville.syrjala@linux.intel.com> (raw)

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

If either of the bigjoiner pipes needs a modeset then we need
a modeset on both pipes. Make it so.
