From 5117348dea5e3ecbb785cfa1271386fb49332b41 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 12 Feb 2011 11:51:03 +0100 Subject: [PATCH] x86: Readd missing irq_to_desc() in fixup_irq() commit a3c08e5d(x86: Convert irq_chip access to new functions) accidentally zapped desc = irq_to_desc(irq); in the vector loop. So we lock some random irq descriptor. Add it back.
