[PATCH 5.10 178/717] soc: ti: knav_qmss: fix reference leak in knav_queue_probe

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit ec8684847d8062496c4619bc3fcff31c19d56847 ]

pm_runtime_get_sync will increment pm usage counter even it
failed. Forgetting to pm_runtime_put_noidle will result in
reference leak in knav_queue_probe, so we should fix it.

Fixes: 41f93af900a20 ("soc: ti: add Keystone Navigator QMSS driver")
