Subject: [PATCH v10 11/13] memory: mtk-smi: Get rid of mtk_smi_larb_get/put
Date:   Mon, 17 Jan 2022 15:05:08 +0800
Message-ID: <20220117070510.17642-12-yong.wu@mediatek.com>
In-Reply-To: <20220117070510.17642-1-yong.wu@mediatek.com>
References: <20220117070510.17642-1-yong.wu@mediatek.com>
MIME-Version: 1.0
Content-Type: text/plain
Precedence: bulk

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.
