Subject[PATCH v2 12/15] PCI: cadence: Remove pci_epf_linkup from Cadence EP driver
Date
pci_epf_linkup is intended to be invoked if the EPC supports linkup
notification. Now that pci-epf-test uses get_features callback, which
indicates Cadence EP driver doesn't support linkup notification, remove
pci_epf_linkup from Cadence EP driver.
