Hi Maxim and Jarkko,

I'm almost OK with this patchset, except that
Documentation/ABI/testing/sysfs-bus-optee-devices needs to be updated
for the new kernel version and TEE mailing list which we're changing right
now.

The last patch touches files I'm not maintainer of. That patch depends
on the previous patches so it makes sense to keep them together.  If a
TPM device driver maintainer would ack that patch I can take it via my
tree. Or we can do it the other way around (with a v9 patchset),
whichever is preferred.

Cheers,
Jens
