Subject: [PATCH v4 4/6] iommu: Stop deferring probe at end of initcalls
Date: Mon, 9 Jul 2018 09:41:51 -0600 [thread overview]
Message-ID: <20180709154153.15742-5-robh@kernel.org> (raw)
In-Reply-To: <20180709154153.15742-1-robh-DgEjT+Ai2ygdnm+yROfE0A@public.gmane.org>
The IOMMU subsystem has its own mechanism to not defer probe if driver
support is missing. Now that the driver core supports stopping deferring
probe if drivers aren't built-in (and probed), use the driver core
support so the IOMMU specific support can be removed.
