From b9ae16d80a357c88fcb7ff6831cfdc196f0a34dd Mon Sep 17 00:00:00 2001 From: Jean-Philippe Brucker Date: Wed, 17 Apr 2019 19:24:41 +0100 Subject: [PATCH] PCI: Add a stub for pci_ats_disabled() Currently pci_ats_disabled() is only defined when CONFIG_PCI is enabled. Since we're about to use the function in the Arm SMMUv3 driver, which could be built with CONFIG_PCI disabled, add a definition of pci_ats_disabled() for !CONFIG_PCI.
