From 26ff46c6f23bb1497aaa1364a5c73a109493b653 Mon Sep 17 00:00:00 2001 From: Myron Stowe Date: Tue, 11 Nov 2014 08:04:50 -0700 Subject: [PATCH] PCI: Remove fixed parameter in pci_iov_resource_bar() pci_iov_resource_bar() always sets its 'pci_bar_type' parameter to 'pci_bar_unknown'. Drop the parameter and just use 'pci_bar_unknown' directly in the callers. No functional change intended.
