   4 Subject: [PATCH 55/70] PCI: designware: Remove PCI_PROBE_ONLY handling
   5
   6 The PCIe designware host driver is not used in system configurations
   7 requiring the PCI_PROBE_ONLY flag to be set to prevent resources
   8 assignment, therefore the driver code handling the flag can be removed
   9 from the kernel.
