No, not without also showing those modules.

This change is not for in-tree kernel module. It's for modules built
outside of kernel tree modules.
Is it really required to show out tree kernel modules ?

Typically we don't add EXPORTs for functions not used in in-tree
modules.

We changed our design and planned to have our module in-tree kernel
instead of out tree kernel module.
Below is the reference for in-tree kernel module proposal for
"drviers/gpu/msm" which is referring to plist_* symbols.
https://source.codeaurora.org/quic/la/kernel/msm-4.9/tree/drivers/gpu/msm/adreno_dispatch.c?h=msm-4.9#n533
Could you please revisit the patch and approve for upstream.

I could not find where you actually use the priority. In any case, the
normal way is to submit the export patch along with the patches that use
it.
Please post the lot to the appropriate lists and people and go from there.
Also, you're missing all the SPDX tags, see Documentation/process/license-rules.rst
