Subject: [RFC/PATCH 3/4] iommu: Export core IOMMU functions to kernel modules
Date: Fri, 17 May 2019 11:47:36 -0700 [thread overview]
Message-ID: <1558118857-16912-4-git-send-email-isaacm@codeaurora.org> (raw)
In-Reply-To: <1558118857-16912-1-git-send-email-isaacm@codeaurora.org>
IOMMU drivers that can be compiled as modules need to use
some of the IOMMU core functions, so expose them.
Signed-off-by: Isaac J. Manjarres <isaacm@codeaurora.org>
