From 8135591e90c81462a6902f6ffa1f1ca021db077a Mon Sep 17 00:00:00 2001 From: Ian Campbell Date: Fri, 18 Feb 2011 16:43:33 +0000 Subject: [PATCH] xen: events: refactor xen_create_msi_irq slightly Calling PHYSDEVOP_map_pirq earlier simplifies error handling and starts to make the tail end of this function look like xen_bind_pirq_msi_to_irq.
