Subject: [PATCH v4 4/4] irqchip/gic-v3-its: Add handling of PCI requester id.
Date: Thu, 1 Oct 2015 17:50:25 -0700 [thread overview]
Message-ID: <1443747025-9918-5-git-send-email-ddaney.cavm@gmail.com> (raw)
In-Reply-To: <1443747025-9918-1-git-send-email-ddaney.cavm@gmail.com>
From: David Daney <david.daney@cavium.com>
Replace open coded generation PCI/MSI requester id with call to the
new function pci_msi_domain_get_msi_rid() which applies the "msi-map"
to the id value.
