Subject: [PATCH v3 12/13] PCI/ATS: Add PASID stubs
Date: Mon, 9 Dec 2019 19:05:13 +0100 [thread overview]
Message-ID: <20191209180514.272727-13-jean-philippe@linaro.org> (raw)
In-Reply-To: <20191209180514.272727-1-jean-philippe@linaro.org>
The SMMUv3 driver, which may be built without CONFIG_PCI, will soon gain
PASID support. Partially revert commit c6e9aefbf9db ("PCI/ATS: Remove
unused PRI and PASID stubs") to re-introduce the PASID stubs, and avoid
adding more #ifdefs to the SMMU driver.
