Subject: [PATCH v2 1/6] PCI/ATS: Export symbols of PASID functions
Date: Mon, 24 Feb 2020 17:58:41 +0100 [thread overview]

In-Reply-To: <20200224165846.345993-1-jean-philippe@linaro.org>
The Arm SMMUv3 driver uses pci_{enable,disable}_pasid() and related
functions. Export them to allow the driver to be built as a module.
