Hey Nick,

FYI $subject seems wrong, this is a PCI patch AFAICT.

This patch should not been needed, there's an existing patch to make
this a module:
https://lore.kernel.org/linux-riscv/20230111125323.1911373-4-daire.mcnamara@microchip.com/

I don't really get this one though, why leave it there as
"documentation" when the file has an SPDX entry anyway?

One for the future:
How about also CCing those listed in MAINTAINERS for the file you're
changing?

Cheers,
Conor.
