Subject: [PATCH 12/13] iommu/virtio: Clean up bus_set_iommu()
Date: Thu, 14 Apr 2022 13:42:41 +0100 [thread overview]
Message-ID: <4db34a35e07f3741a658465045b78c96a569c591.1649935679.git.robin.murphy@arm.com> (raw)
In-Reply-To: <cover.1649935679.git.robin.murphy@arm.com>
Stop calling bus_set_iommu() since it's now unnecessary, and simplify
the probe failure path accordingly.
