From 5643e47700d3c1b2a8a1aca56629f12e90df407c Mon Sep 17 00:00:00 2001
From: Dave Stevenson <dave.stevenson@raspberrypi.org>
Date: Wed, 12 Jun 2019 17:13:21 +0100
Subject: [PATCH] drm/vc4: In FKMS look at the modifiers correctly for
SAND
Incorrect masking was used in the switch for the modifier,
therefore for SAND (which puts the column pitch in the
modifier) it didn't match.
