Subject: [PATCH v7 27/36] iommu/mediatek: Remove mtk_iommu.h
Date: Tue, 3 May 2022 15:14:18 +0800	[thread overview]
Message-ID: <20220503071427.2285-28-yong.wu@mediatek.com> (raw)
In-Reply-To: <20220503071427.2285-1-yong.wu@mediatek.com>

Currently there is a suspend structure in the header file. It's no need
to keep a header file only for this. Move these into the c file and rm
this header file.
