Subject: [PATCH v3 4/6] iommu: Stop deferring probe at end of initcalls
Date: Thu, 28 Jun 2018 14:43:42 -0600 [thread overview]
Message-ID: <20180628204344.13973-5-robh@kernel.org> (raw)
In-Reply-To: <20180628204344.13973-1-robh@kernel.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.
