Subject: [PATCH 19/21] iommu/mediatek: Adjust the structure
Date: Sat, 11 Jul 2020 14:48:44 +0800	[thread overview]
Message-ID: <20200711064846.16007-20-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200711064846.16007-1-yong.wu@mediatek.com>

Add "struct mtk_iommu_data *" in the "struct mtk_iommu_domain",
reduce the call mtk_iommu_get_m4u_data().
No functional change.
