Several early probe failures then unwind through wanxl_pci_remove_one(), including failure to allocate the coherent status area or to restore the DMA mask. wanxl_pci_remove_one() unconditionally calls wanxl_reset(), and wanxl_reset() dereferences card->plx. On those early failures card->plx is still NULL, so the error path can dereference a NULL MMIO pointer. Only issue the hardware reset once the BAR mapping exists. The remaining cleanup in wanxl_pci_remove_one() already checks whether later resources were allocated. This issue was found by a static analysis checker and confirmed by manual source review.
