From e387b9eefe89a23245f2446f947529cce5d6db35 Mon Sep 17 00:00:00 2001 From: Michael Ellerman Date: Thu, 22 Mar 2007 21:51:27 +1100 Subject: [PATCH] MSI: Simplify BUG() handling in pci_disable_msi() Although it might be nice to do a printk before BUG'ing, it's really not necessary, and it complicates the code.
