[PATCH 6.1 0056/1146] soc: ti: knav_qmss_queue: Fix PM disable depth imbalance in knav_queue_probe

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

 



From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit e961c0f19450fd4a26bd043dd2979990bf12caf6 ]

The pm_runtime_enable will increase power disable depth. Thus
a pairing decrement is needed on the error handling path to
keep it balanced according to context.
