From 983bfb5b40157c9fbb7c5290508f18845b7e7234 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Tue, 10 Jul 2012 14:57:55 -0700 Subject: [PATCH] [SCSI] qla4xxx: remove unnecessary read of PCI_CAP_ID_EXP The PCIE capability offset is saved during PCI bus walking. It will remove an unnecessary search in the PCI configuration space if this value is referenced instead of reacquiring it.
