Date: Tue, 6 Oct 2015 18:03:58 +0100 From: Marc Zyngier <marc.zyngier@....com> To: Rob Herring <robh+dt@...nel.org>, Jason Cooper <jason@...edaemon.net>, Thomas Gleixner <tglx@...utronix.de>, Bjorn Helgaas <bhelgaas@...gle.com> Cc: linux-kernel@...r.kernel.org, linux-arm-kernel@...ts.infradead.org, linux-pci@...r.kernel.org, Mark Rutland <Mark.Rutland@....com>, David Daney <ddaney.cavm@...il.com>, Robin Murphy <robin.murphy@....com> Subject: [PATCH v2 3/8] PCI/MSI: Use of_msi_get_domain instead of open-coded "msi-parent" parsing Now that we have a function that implements the complexity of the "msi-parent" property parsing, switch to that.
