Subject: [PATCH v5 24/25] PCI/ATS: Export PRI functions
Date: Tue, 14 Apr 2020 19:02:52 +0200	[thread overview]
Message-ID: <20200414170252.714402-25-jean-philippe@linaro.org> (raw)
In-Reply-To: <20200414170252.714402-1-jean-philippe@linaro.org>

The SMMUv3 driver uses pci_{enable,disable}_pri() and related
functions. Export those functions to allow the driver to be built as a
module.
