Subject: [PATCH v4 08/16] iommu: Introduce accessors for iommu private data
Date: Thu, 26 Mar 2020 16:08:33 +0100
Message-ID: <20200326150841.10083-9-joro@8bytes.org> (raw)
In-Reply-To: <20200326150841.10083-1-joro@8bytes.org>

From: Joerg Roedel <jroedel@suse.de>

Add dev_iommu_priv_get/set() functions to access per-device iommu
private data. This makes it easier to move the pointer to a different
location.
