Zijun Hu b50b631d8f PCI: endpoint: Clear secondary (not primary) EPC in pci_epc_remove_epf() ... commit 688d2eb4c6 upstream. In addition to a primary endpoint controller, an endpoint function may be associated with a secondary endpoint controller, epf->sec_epc, to provide NTB (non-transparent bridge) functionality. Previously, pci_epc_remove_epf() incorrectly cleared epf->epc instead of epf->sec_epc when removing from the secondary endpoint controller. Extend the epc->list_lock coverage and clear either epf->epc or epf->sec_epc as indicated.
