Hello arm-soc maintainers,

Please pull these OP-TEE driver fixes. There's one user-after-free issue if
in the error handling path when the OP-TEE driver is initializing. There's
also one fix to to register dynamically allocated shared memory needed by
kernel clients communicating with secure world via memory references.

If you think it's too late for v5.4 please queue it for v5.5 instead.

Thanks,
Jens

Please ignore this pull request.

"tee: optee: Fix dynamic shm pool allocations" is not good without other
patches, which are not included here.

Sorry about the mess.

Thanks,
Jens
