From 5757a769ea4e094df6ec92d9ce7d05a90d5bf3e6 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Mon, 3 Feb 2014 14:27:39 -0700 Subject: [PATCH] PCI: Add pci_dev_flag for ACS enable quirks Quirks that enable ACS-compatible functionality on a device need some way to track whether a given device has been enabled. Rather than create new data structures for this, allocate one of the pci_dev_flags to indicate this setup.
