It is allowed to be called with spinlocks held, but the same lock is not allowed to be acquired in complete handler.

If yes, many hc drivers are still involved to be modified. thanks, -- Ming Lei -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
