You pointed out previously that port shouldn't be used in probe(). That made me implement new helpers cp210x_write_u16_reg and cp210x_read_u16_reg that don't use port. Probe() now calls cp210x_activate_workarounds which in turn calls these new helpers. An alternative would be to call usb_control_msg from cp210x_activate_workarounds, but I think it would make it look pretty ugly. -- 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
