[PATCH AUTOSEL 5.10 011/217] crypto: omap-aes - fix the reference count leak of omap device

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

 



From: Zhang Qilong <zhangqilong3@xxxxxxxxxx>

[ Upstream commit 383e8a823014532ffd81c787ef9009f1c2bd3b79 ]

pm_runtime_get_sync() will increment  pm usage counter even
when it returns an error code. We should call put operation
in error handling paths of omap_aes_hw_init.
