The issue is that USB_OTG_FSM is tristate but FSL_USB2_OTG is a bool so we end up with a built in driver depending on a module. Unfortunately I can't see why this triggered now. Neither file nor their Kconfig has changed for quite some time so I guess we lost some other config that was forcing USB_OTG_FSM to be built in.
