The hc_driver.irq is included in usb_hcd_irq. Hm, that's correct. I'll dive in and see if there's any other way around. I think I saw IRQF_DISABLED somewhere there, but that might be just some phantom. Either way, is this direction I'm taking the correct one (have irq handler in imx-otg and send IRQs to gadget/host drivers from there)? Also, any other comments about this patchset before I roll out another version? Thanks!
