Subject: [PATCH v2 07/12] media: mtk-vcodec: Get rid of mtk_smi_larb_get/put
Date: Mon, 10 Jun 2019 20:55:08 +0800 [thread overview]
Message-ID: <1560171313-28299-8-git-send-email-yong.wu@mediatek.com> (raw)
In-Reply-To: <1560171313-28299-1-git-send-email-yong.wu@mediatek.com>
MediaTek IOMMU has already added the device_link between the consumer
and smi-larb device. If the vcodec device call the pm_runtime_get_sync,
the smi-larb's pm_runtime_get_sync also be called automatically.
