| Subject: drm: atmel-hlcdc: actually disable scaling when no scaling is required |
| |
| 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. |
