Subject: [PATCH 02/23] iommu/amd: Move 'struct dma_ops_domain' definition to amd_iommu.c
Date: Tue, 22 Dec 2015 23:21:07 +0100 [thread overview]
Message-ID: <1450822888-22590-3-git-send-email-joro@8bytes.org> (raw)
In-Reply-To: <1450822888-22590-1-git-send-email-joro@8bytes.org>
From: Joerg Roedel <jroedel@suse.de>
It is only used in this file anyway, so keep it there. Same
with 'struct aperture_range'.
