[PATCH AUTOSEL 6.0 36/39] drm/amd/display: Use viewport height for subvp mall allocation size

[Sasha Levin <sashal@kernel.org>]

From: Dillon Varone <Dillon.Varone@amd.com>

[ Upstream commit dd2c028c1395d622df7ddd6837f8ab2dc94008ee ]

[WHY?]
MALL allocation size depends on the viewport height, not the addressable
vertical lines, which will not match when scaling.

[HOW?]
Base MALL allocation size calculations off viewport height.
