Subject: [PATCH v2 6/8] iommu: Stop deferring probe at end of initcalls
Date: Thu, 24 May 2018 12:50:22 -0500	[thread overview]
Message-ID: <20180524175024.19874-7-robh@kernel.org> (raw)
In-Reply-To: <20180524175024.19874-1-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.
