From 9670ee752727945d8ce4f76efc0b68364b832f20 Mon Sep 17 00:00:00 2001 From: Pierre Morel Date: Mon, 26 Oct 2020 11:34:39 -0400 Subject: s390x/pci: use a PCI Function structure We use a ClpRspQueryPci structure to hold the information related to a zPCI Function. This allows us to be ready to support different zPCI functions and to retrieve the zPCI function information from the host.
