Thanks for the patch. Looks good, but please fix up the two minor issues
pointed out below and resend, and I'll apply it after the merge window
closes.

Since you are the one submitting the patch your SoB should go last. We
have a Co-developed-by tag which can you use to indicate co-authorship
(the second SoB is still required). The documentation for this was
recently updated in commit
24a2bb90741b ("docs: Clarify the usage and sign-off requirements for Co-developed-by")

We're trying to move away from adding product-id defines, so please just
use a constant here as most ZTE entries do and add a short comment after
the entry. It's fine to go above 80 columns here even if checkpatch.pl
complains.
