Subject: [PATCH v3 05/14] iommu/amd: Declare functions as extern
Date: Sun,  4 Oct 2020 01:45:40 +0000	[thread overview]
Message-ID: <20201004014549.16065-6-suravee.suthikulpanit@amd.com> (raw)
In-Reply-To: <20201004014549.16065-1-suravee.suthikulpanit@amd.com>

And move declaration to header file so that they can be included across
multiple files. There is no functional change.
