Subject: [PATCH v2 12/15] drm/i915: Simplify intel_initial_plane_config() calling convention
Date: Fri, 15 Dec 2023 12:59:26 +0200	[thread overview]
Message-ID: <20231215105929.29568-13-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20231215105929.29568-1-ville.syrjala@linux.intel.com>

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

There's no reason the caller of intel_initial_plane_config() should
have to loop over the CRTCs. Pull the loop into the function to
make life simpler for the caller.
