From 00a30b254b88d2d4f5af00835a9b7f70326def9b Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Thu, 24 Mar 2011 22:53:10 +0100 Subject: x86: DT: Fix return condition in irq_create_of_mapping() The xlate() function returns 0 or a negative error code. Returning the error code blindly will be seen as an huge irq number by the calling function because irq_create_of_mapping() returns an unsigned value. Return 0 (NO_IRQ) as required.
