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