Subject: [PATCH v2 21/23] iommu/mediatek: Adjust the structure
Date: Sat, 5 Sep 2020 16:09:18 +0800 [thread overview]
Message-ID: <20200905080920.13396-22-yong.wu@mediatek.com> (raw)
In-Reply-To: <20200905080920.13396-1-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.
