Subject: [PATCH v7 10/12] memory: mtk-smi: Get rid of mtk_smi_larb_get/put
Date: Fri, 30 Jul 2021 10:52:36 +0800	[thread overview]
Message-ID: <20210730025238.22456-11-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210730025238.22456-1-yong.wu@mediatek.com>

After adding device_link between the iommu consumer and smi-larb,
the pm_runtime_get(_sync) of smi-larb and smi-common will be called
automatically. we can get rid of mtk_smi_larb_get/put.
