- Fix dma_chan direction in data transfer test (Yoshihiro Shimoda)

- Return pci_epf_type_add_cfs() error if EPF has no driver (Damien Le Moal)

- Add kernel-doc for pci_epc_raise_irq() and pci_epc_map_msi_irq() MSI
  vector parameters (Manivannan Sadhasivam)

- Pass EPF device ID to driver probe functions (Manivannan Sadhasivam)

- Return -EALREADY if EPC has already been started/stopped (Manivannan
  Sadhasivam)

- Add linkdown notifier support and use it in qcom-ep (Manivannan
  Sadhasivam)

- Add Bus Master Enable event support and use it in qcom-ep (Manivannan
  Sadhasivam)
