Subject: [PATCH v11 23/23] iommu/mediatek: Clean up struct mtk_smi_iommu
Date: Sat, 24 Aug 2019 11:02:08 +0800 [thread overview]
Message-ID: <1566615728-26388-24-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1566615728-26388-1-git-send-email-yong.wu@mediatek.com>
Remove the "struct mtk_smi_iommu" to simplify the code since it has only
one item in it right now.
