Subject: [PATCH 2/2] iommu: Implement a dummy bus_set_iommu()
Date: Fri, 1 Aug 2014 14:45:13 +0200 [thread overview]
Message-ID: <1406897113-20099-2-git-send-email-thierry.reding@gmail.com> (raw)
In-Reply-To: <1406897113-20099-1-git-send-email-thierry.reding-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>
From: Thierry Reding <treding-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org>
This allows IOMMU drivers to compile even if IOMMU_API is not selected
and helps improve compile coverage.
