From 821be9dbb220389eaa6857705e1df9e64888138f Mon Sep 17 00:00:00 2001 From: Knut Omang Date: Sun, 24 Aug 2014 15:32:18 +0200 Subject: [PATCH] pcie: Rename the pcie_cap_ari_* functions to pcie_cap_arifwd_* Rename helper functions to make a clearer distinction between the PCIe capability/control register feature ARI forwarding and a device that supports the ARI feature via an ARI extended PCIe capability.
