4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Zhipeng Lu <alexious@xxxxxxxxxx>
[ Upstream commit c2709b2d6a537ca0fa0f1da36fdaf07e48ef447d ]
When radeon_bo_create and radeon_vm_clear_bo fail, the vm->page_tables
allocated before need to be freed. However, neither radeon_vm_init
itself nor its caller have done such deallocation.
Fixes: 6d2f2944e95e ("drm/radeon: use normal BOs for the page tables v4")
