tee_drv.h references struct device, but does not include device.h nor platform_device.h. Therefore, if tee_drv.h is included by some file that does not pull device.h nor platform_device.h beforehand, we have a compile warning. Fix this by adding a forward declaration.

Looks good to me.

Do we need this to fix a warning in mainline, in linux-next, or only in combination with some other patches?
I have not run into this warning in my build testing.

Can you pick up the patch in your git tree and send a pull request for the appropriate release (4.12-fixes or 4.13)?
If you don't expect to send anything else for tee in that release, you can also forward the patch to arm@kernel.org and ask for inclusion. If you just reply with the 'Reviewed-by', I would not expect to have to do anything in the arm-soc tree.

Only with some other patches.
Ok, in that case, Jens can just queue up the patch in his tree now, and it will be there in time when other patches get applied on top, no need to have this in arm-soc by itself.
