Dear Sir, Actually, I find that psmouse_attr_set_protocol checks psmouse_switch_protocol's return vaule, but psmouse_connect does not. So I let psmouse_switch_protocol() in psmouse_connect return -1 in purpose to test the robustness of psmouse driver. However, psmouse_switch_protocol() in psmouse_connect gets NULL as protocol and it will not fail. I think you are right, and this error is unreal. Thank you very much! -- Jia-Ju Bai -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
