Subject: [PATCH 10/13] memory: mtk-smi: Get rid of mtk_smi_larb_get/put
Date: Tue, 1 Jan 2019 12:51:13 +0800	[thread overview]
Message-ID: <1546318276-18993-11-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1546318276-18993-1-git-send-email-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.
