Send a patch backporting the driver to the 4.19 kernel. There's a write-up
on sending kernel patches for OpenBMC here:

https://github.com/openbmc/docs/blob/master/kernel-development.md

That document is pretty out of date (from a quick read), so have a browse
through the wiki as well:

However I expect we'll be moving to the 5.0 kernel once it's released, and
that will solve your problem. I've added Joel on To: who might be able to
elaborate on the timing for 5.0 in OpenBMC. 5.0-rc8 was pushed 69
minutes ago, so there's still probably another week or so before the
upstream release.
