Subject: [PATCH v5 07/16] media: mtk-mdp: Use pm_runtime_resume_and_get for PM get_sync
Date: Sat, 10 Apr 2021 17:11:19 +0800 [thread overview]
Message-ID: <20210410091128.31823-8-yong.wu@mediatek.com> (raw)
In-Reply-To: <20210410091128.31823-1-yong.wu@mediatek.com>
pm_runtime_get_sync will increment pm usage counter even it failed.
This patch use pm_runtime_resume_and_get instead of pm_runtime_get
to keep usage counter balanced.
