Subject: [RFC 8/9] drivers: of: call iommu_bus_add_dev after iommu_configure_ops
Date: Mon, 25 Apr 2016 21:28:13 +0530 [thread overview]
Message-ID: <1461599894-1969-9-git-send-email-sricharan@codeaurora.org> (raw)
In-Reply-To: <1461599894-1969-1-git-send-email-sricharan-sgV2jX0FEOL9JmXXK+q4OQ@public.gmane.org>
Now that the device's iommu ops are configured at probe time,
the device has to be added to the iommu late.
