From 04d35d7324ed35983189bd396db7874a50bbea43 Mon Sep 17 00:00:00 2001 From: Helge Deller Date: Tue, 10 Jan 2006 20:47:50 -0500 Subject: [PATCH] [PARISC] Fix Cirrus 6832 Cardbus on RDI Tadpole PARISC Laptop Fix irq-off-by-one for Cirrus 6832 Cardbus on RDI Tadpole PARISC Laptop. We just DECLARE_PCI_FIXUP_ENABLE as it is unlikely that this will be found in any other parisc system.
