From c24817b6babd4b966e68db536c004949bf24dae7 Mon Sep 17 00:00:00 2001 From: Ethan Zhao Date: Tue, 22 Jul 2014 18:36:43 +0000 Subject: [PATCH] i40e: use global pci_vfs_assigned() to replace local i40e_vfs_are_assigned() There is global funcion pci_vfs_assigned(), so use it instead of composing local one.
