From: Ray Strode rstrode@redhat.com Date: Mon, 27 Nov 2017 16:50:09 -0500 Subject: drm/qxl: unref cursor bo when finished with it
From: Ray Strode rstrode@redhat.com
commit 16c6db3688734b27487a42d0c2a1062d0b2bad03 upstream.
qxl_cursor_atomic_update allocs a bo for the cursor that it never frees up at the end of the function.
This commit fixes that.
