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")
I believe this should be Fixes: 4615e5a34b95 ("optee: add FF-A support") don't you agree?
Thanks, Jens
