#1450058 — [PATCH 4.6 134/203] drm: atmel-hlcdc: actually disable scaling when no scaling is required

4.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Boris Brezillon <boris.brezillon@free-electrons.com>

commit 1b7e38b92b0bbd363369f5160f13f4d26140972d upstream.

The driver is only enabling scaling, but never disabling it, thus, if you
enable the scaling feature once it stays enabled forever.
