#     drm/ttm: fix ttm pool initialization for no-dma-device drivers
#     
#     The QXL driver doesn't use any device for DMA mappings or allocations so
#     dev_to_node() will panic inside ttm_device_init() on NUMA systems:
#     
#       general protection fault, probably for non-canonical address 0xdffffc000000007a: 0000 [#1] PREEMPT SMP KASAN NOPTI
