Subject: [PATCH 03/12] drm/i915: Introduce some local intel_dp variables
Date: Wed, 19 Feb 2020 22:35:35 +0200	[thread overview]
Message-ID: <20200219203544.31013-4-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20200219203544.31013-1-ville.syrjala@linux.intel.com>

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

The drrs code dereferences mode->vrefresh via some really long chain
of structures/pointers. Couldn't get coccinelle to see through all
that so let's add some local variables to help it.
