You need to change a lot more than this. See commit a76dd463c58e (USB:
EHCI: make ehci-orion a separate driver) as an example of what is
needed. In the end, ehci-fsl.ko should be a new driver module, not
compiled into ehci-hcd.ko.

Why do you want to override driver->start? The default value
for this field is already set to ehci_run.
