4.15-stable review patch. If anyone has any objections, please let me know. ------------------ From: Ray Strode <rstrode@xxxxxxxxxx> 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.
