Subject: [PATCH v3 09/14] memory: mtk-smi: Get rid of mtk_smi_larb_get/put
Date: Tue, 3 Sep 2019 17:37:31 +0800 [thread overview]
Message-ID: <1567503456-24725-10-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1567503456-24725-1-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.
