From: Suman Anna <s-anna@ti.com> stable inclusion from stable-5.10.50 commit c3285441b4cd9b7ab759dfcb3164e4825656326c bugzilla: 174522 https://gitee.com/openeuler/kernel/issues/I4DNFY Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=... -------------------------------- [ Upstream commit 5c8552325e013cbdabc443cd1f1b4d03c4a2e64e ] The pm_runtime APIs added first in commit 7694b6ca649f ("crypto: sa2ul - Add crypto driver") are not unwound properly and was fixed up partially in commit 13343badae09 ("crypto: sa2ul - Fix PM reference leak in sa_ul_probe()"). This fixed up the pm_runtime usage count but not the state. Fix this properly.
