Subject: [PATCH 0/3] dmaengine: stm32: fix reference leak
Date: Fri, 27 Nov 2020 17:45:22 +0800 [thread overview]
Message-ID: <20201127094525.121388-1-miaoqinglang@huawei.com> (raw)
pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to putting operation will result in a
reference leak here.
Use pm_runtime_resume_and_get to fix it.
