Subject: [PATCH v4 07/18] iommu: exynos: remove unused functions
Date: Fri, 16 Jan 2015 10:13:01 +0100	[thread overview]
Message-ID: <1421399592-7482-8-git-send-email-m.szyprowski@samsung.com> (raw)
In-Reply-To: <1421399592-7482-1-git-send-email-m.szyprowski@samsung.com>

This patch removes two unneeded functions, which are not a part of
generic IOMMU API and were never used by any other driver.
