This is a new file - it did not exist in v1 - thus you had to write it.
If you wrote it, you (or your employer) hold all copyrights, so yes, you
(or your employer) can relicense it.

I cannot imagine the case why employer would not like to have dual
license here (it's beneficial to him, so employer would be acting
against himself), but if you need to convince him, you can just say,
that contributing to Open Source project means accepting the licenses in
that project. The license for new bindings in this project is (GPL-2.0
or BSD-2), like pointed by checkpatch.

Best regards,
