SubjectRe: [RFC][PATCH v2 05/13] usb: otg: add OTG core
From
Date
(This will go into a minor detail. That's probably not what you want
when posting an RFC. But this patch got caught by an email filter I use
and a future, non-RFC, version will get caught too. So I decided to
bother you with this now.)

This creates a module usb-otg.ko if CONFIG_USB_OTG_CORE is 'm', built
from just usb-otg.c.

This code adds no MODULE_LICENSE() macro in this patch and usb-otg.ko
will carry no license field. So I think the loading of that module
(triggered by loading another module that uses one of the exported
symbols, I suppose) taints the kernel. Am I correct?
