Subject: [PATCH] PCI: dwc: pci-dra7xx: fix runtime pm imbalance on error
Date: Wed, 20 May 2020 16:47:56 +0800 [thread overview]
Message-ID: <20200520084756.31620-1-dinghao.liu@zju.edu.cn> (raw)
pm_runtime_get_sync() increments the runtime PM usage counter even
it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced.
