Subject: [PATCH v3 05/14] media: mtk-jpeg: Get rid of mtk_smi_larb_get/put
Date: Tue, 3 Sep 2019 17:37:27 +0800	[thread overview]
Message-ID: <1567503456-24725-6-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1567503456-24725-1-git-send-email-yong.wu@mediatek.com>

MediaTek IOMMU has already added device_link between the consumer
and smi-larb device. If the jpg device call the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.
