Both the OP-TEE core and some OP-TEE drivers use an if/else expression
to check a boolean which can instead be returned directly. Implement
this change.

Hi,
I've just rebased the linaro-swg/kernel optee branch on v6.18 from
v6.14. By rebasing, we eliminated a few workarounds on the optee
branch and gained FF-A version 1.2 support in the kernel.
Cheers,
Jens
Hello arm-soc maintainers,
Please pull these two patches adding a generic TEE revision sysfs
attribute and implement support for OP-TEE.
Thanks,
Jens

Hello arm-soc maintainers,
Please pull these updates adding TEE bus callbacks to let the users of
the bus get rid of the struct device_driver callbacks .probe(),
.remove() and .shutdown().
The maintainers for the updated drivers using the TEE bus have agreed to
take these changes via my tree, with the exception of the maintainer for
drivers/firmware/broadcom/tee_bnxt_fw.c, who has remained silent during
the review. However, the changes in the drivers are straight forward so
it's better to take these patches too rather than excluding them.
Further details are in the last patch set:

Jens
