Subject: [PATCH v8 8/9] PCI/ATS: Export PRI functions
Date: Thu, 12 Nov 2020 13:55:20 +0100 [thread overview]
Message-ID: <20201112125519.3987595-9-jean-philippe@linaro.org> (raw)
In-Reply-To: <20201112125519.3987595-1-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.
