Subject: [PATCH] crypto: omap-aes - Fix PM disable depth imbalance in omap_aes_probe
Git-commit: ff8107200367f4abe0e5bce66a245e8d0f2d229e
Patch-mainline: v5.11-rc1
References: git-fixes
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.
Fixes: f7b2b5dd6a62a ("crypto: omap-aes - add error check for pm_runtime_get_sync")
