Subject: [PATCH] x86/PCI: Apply VMD's AERSID fixup generically
Date: Fri,  7 Sep 2018 13:22:30 -0600	[thread overview]
Message-ID: <1536348150-3535-1-git-send-email-jonathan.derrick@intel.com> (raw)

A root port device-id changed between simulation and production. Rather
than match device-ids which may not be future-proof if left
unmaintained, match all root ports which exist in a VMD-domain
