Re: [PATCH 0/3] PSP TEE driver update and bug fixes

The first patch helps to improve the response time by reducing the
polling time of the tee command status variable.

Second patch is a bug fix to handle multi-threaded use-case.
During testing, race condition was seen due to missing synchronisation
in writes to the TEE ring buffer. This patch helps to resolve that.

Third patch is to update the copyright year for the tee driver files.

Just something to think about and not as part of this patch series, but
think about submitting a patch that adds you as maintainer of the TEE
portion of the driver (see how the SEV portion is handled).

Thanks,
Tom
