From 973ca1329ac445e55135e01874118d4e28392ea7 Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.org>

Subject: [PATCH] drm: vc4: Programming the CTM is conditional on
running full KMS
vc4_ctm_commit writes to HVS registers, so this is only applicable
when in full KMS mode, not in firmware KMS mode. Add this conditional.
