[PATCH 5.17 066/225] tee: optee: add missing mutext_destroy in optee_ffa_probe

From: Greg Kroah-Hartman
Date: Wed May 04 2022 - 13:33:39 EST


From: Dongliang Mu <mudongliangabcd@xxxxxxxxx>

[ Upstream commit b5e22886839ae466fcf03295150094516c0fd8eb ]

The error handling code of optee_ffa_probe misses the mutex_destroy of
ffa.mutex when mutext_init succeeds.

Fix this by adding mutex_destory of ffa.mutex at the error handling part

Fixes: aceeafefff73 ("optee: use driver internal tee_context for some rpc")
