From 305b3228f9ff4d59f49e6d34a7034d44ee8ce2f0 Mon Sep 17 00:00:00 2001 From: David Vrabel Date: Thu, 19 Jan 2006 17:52:27 +0000 Subject: [PATCH] [PATCH] driver core: platform_get_irq*(): return -ENXIO on error platform_get_irq*() cannot return 0 on error as 0 is a valid IRQ on some platforms, return -ENXIO instead.
