From f01f969e25ecc6f88844bcdd63f1f27610418bbc Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Fri, 18 Aug 2017 20:27:54 +0530 Subject: [PATCH] PCI: endpoint: Add an API to get matching "pci_epf_device_id" Add an API to get "pci_epf_device_id" matching the EPF name. This can be used by the EPF driver to get the driver data corresponding to the EPF device name.
