From 97ffab1f14638d2c95ad986ce735481d164a0bd2 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Wed, 6 Jul 2011 13:03:35 -0400 Subject: xen/pci: Use 'acpi_gsi_to_irq' value unconditionally. In the past we would only use the function's value if the returned value was not equal to 'acpi_sci_override_gsi'. Meaning that the INT_SRV_OVR values for global and source irq were different. But it is OK to use the function's value even when the global and source irq are the same.
