Subject: [PATCH V2 1/9] genirq: Export irq_set_msi_desc()
Date: Sun, 26 Nov 2017 01:02:05 +0530	[thread overview]
Message-ID: <1511638333-22951-2-git-send-email-mmaddireddy@nvidia.com> (raw)
In-Reply-To: <1511638333-22951-1-git-send-email-mmaddireddy-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>

PCI MSI driver allocates MSI entry for each pci dev which creates msi_desc,
host driver maps each msi domain with hwirq and then sets msi_desc for
that irq number. Need to export irq_set_msi_desc() to allow Tegra PCIe
driver to be compiled as a loadable kernel module.
