From c7f570a5eca59575572ee231390df727df207bda Mon Sep 17 00:00:00 2001 From: Peter Chubb Date: Tue, 5 Dec 2006 12:25:31 +1100 Subject: [PATCH] [IA64] Fix pci.c kernel compilation breakage. The recent change to convert the is_enabled flag in the PCI device to an atomic count broke the IA64 compilation. As pcibios_disable_device is only ever called if the reference count is zero, convert the if to a BUG_ON.
