Subject: [PATCH v3 34/34] iommu: Unexport iommu_group_get_for_dev()
Date:   Wed, 29 Apr 2020 15:37:12 +0200
Message-Id: <20200429133712.31431-35-joro@8bytes.org>
In-Reply-To: <20200429133712.31431-1-joro@8bytes.org>
References: <20200429133712.31431-1-joro@8bytes.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: Joerg Roedel <jroedel@suse.de>

The function is now only used in IOMMU core code and shouldn't be used
outside of it anyway, so remove the export for it.
