+Subject: MIPS: RC32434: fix broken PCI resource initialization
+From: Gabor Juhos <juhosg@openwrt.org>
+X-Patchwork-Id: 6940
+Message-Id: <1400142944-32147-1-git-send-email-juhosg@openwrt.org>
+To: Ralf Baechle <ralf@linux-mips.org>

+
+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.
