A quick git grep:

$ git grep PCI_ENDPOINT_CONFIGFS

I think we should just merge and send Arnd's fix to Linus for the 7.0
release cycle.

If we want to remove CONFIG_PCI_ENDPOINT_CONFIGFS, it will require changes
in the docs, defconfigs, etc., so it does seem like something that would
have to target 7.1 rather than 7.0.


Kind regards,
