From 62a276f81fca41778abd8cb6d720a36302a89473 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 6 Sep 2013 11:26:24 -0600 Subject: [PATCH] [SCSI] qla2xxx: Use standard PCIe Capability Link register field names Use the standard #defines for PCIe Link Capability register fields rather than bare numbers. This also uses the new PCI Express Capability accessor rather than reading the capability directly.
