+Subject: [PATCH 55/70] PCI: designware: Remove PCI_PROBE_ONLY handling
+
+The PCIe designware host driver is not used in system configurations
+requiring the PCI_PROBE_ONLY flag to be set to prevent resources
+assignment, therefore the driver code handling the flag can be removed
+from the kernel.
