[GIT PULL] tee subsys fixes for v5.4 (take two)

[GIT PULL] tee subsys fixes for v5.4 (take two)

[Jens Wiklander]

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.

"tee: optee: Fix dynamic shm pool allocations" is now from version 2 which
includes a fix up with a small but vital dependency.

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

Thanks,
Jens

Hi,

I noticed you based this on -rc3 -- all our other branches are on -rc2 or
older.

Anyway, I brought this in to the fixes branch, it's the only thing we have
queued up at this time so I'll give it a few days in -next before I send it in.

I'm sorry, I thought -rc3 was old enough. I'll stick to -rc2 or older
in next time.

It looks like the two patches in this pull request
(https://git.linaro.org/people/jens.wiklander/linux-tee.git/tag/?h=tee-fixes-for-v5.4)
are still in -next and haven't got any further. Is there anything
wrong? Something I should fix?

Thanks,
Jens

They were in our fixes branch and didn't go in yet, but will shortly.
