Subject: [Qemu-devel] [PATCH 08/12] spapr_pci: Fold spapr_phb_vfio_reset() into spapr_pci code
Date: Fri, 26 Feb 2016 22:31:59 +1100	[thread overview]
Message-ID: <1456486323-8047-9-git-send-email-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <1456486323-8047-1-git-send-email-david@gibson.dropbear.id.au>

Simplify the sPAPR PCI code by folding spapr_phb_vfio_reset() into
spapr_phb_reset().
