From ae1d884d9e211bf27f9c7e129be9221636bc1198 Mon Sep 17 00:00:00 2001 From: Jon Mason Date: Wed, 11 Sep 2013 15:38:13 -0700 Subject: [PATCH] [SCSI] lpfc: 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. Also, pci_is_pcie is a better way of determining if the device is PCIE or not (as it uses the same saved PCIE capability offset).
