Recently I test linux device drivers 3.17.2, and find some potential bugs. The target file is drivers/input/mouse/psmouse-base.c, which is used to build psmouse.ko. I hope you can help me check my findings: [1] psmouse_switch_protocol is called by psmouse_connect when initializing the driver. However, psmouse_switch_protocol may be failed and return -1, but its return value is not checked in psmouse_connect. In my experiment of running the driver, when psmouse_switch_protocol in psmouse_connect is failed, the system crash will occur. Could you help me check these findings? Thank you very much, and I'm looking forward to your reply. -- 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
