Subject: [PATCH 07/14] iommu: Introduce accessors for iommu private data
Date: Fri, 28 Feb 2020 16:08:13 +0100 [thread overview]
Message-ID: <20200228150820.15340-8-joro@8bytes.org> (raw)
In-Reply-To: <20200228150820.15340-1-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.
