Zijun Hu 97bc165a06 PCI: endpoint: Finish virtual EP removal in pci_epf_remove_vepf() ... commit 3b9f942eb2 upstream. When removing a virtual Endpoint, pci_epf_remove_vepf() failed to clear epf_vf->epf_pf, which caused a subsequent pci_epf_add_vepf() to incorrectly return -EBUSY: pci_epf_add_vepf(epf_pf, epf_vf) // add pci_epf_remove_vepf(epf_pf, epf_vf) // remove pci_epf_add_vepf(epf_pf, epf_vf) // add again, -EBUSY error Fix by clearing epf_vf->epf_pf in pci_epf_remove_vepf().
