From c3bddbda36a74225ad3d04aaa9600a25aff6b98b Mon Sep 17 00:00:00 2001 From: Inki Dae Date: Thu, 21 Nov 2013 12:09:51 +0900 Subject: [PATCH] drm/exynos: g2d: fix memory leak to userptr This patch releases a vma object when cleaning up userptr resources. A new vma object was allocated and copied when getting userptr pages so the new vma object should be freed properly if the userptr pages aren't used anymore.
