From 10c463a7a3b96285133c37e230781a1274abbd31 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Sun, 18 Mar 2012 22:46:26 -0700 Subject: [PATCH] PCI: Kill pci_is_reassigndev() pci_reassigndev_resource_alignment() is the only user of pci_is_reassigndev(). If we just use pci_specified_resource_alignment() directly, we only need to call it once instead of twice, and we can get rid of pci_is_reassigndev() altogether. No functional change.
