Subject: [PATCH v3 2/9] PCI: Add a stub for pci_ats_disabled()
Date: Wed, 17 Apr 2019 19:24:41 +0100 [thread overview]
Message-ID: <20190417182448.12382-3-jean-philippe.brucker@arm.com> (raw)
In-Reply-To: <20190417182448.12382-1-jean-philippe.brucker@arm.com>
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.
