  13 The parent field of the 'rc32434_res_pci_mem1' resource points to
  14 the resource itself which is obviously wrong. Due to the broken
  15 initialitazion, the PCI devices on the Mikrotik RB532 boards are
  16 not working since commit 22283178 (MIPS: avoid possible resource
  17 conflict in register_pci_controller).
  18
  19 Remove the field initialization to fix the issue.
