i have already added some pr_err to the kernel source , then the dmesg say : the touchpad work 1 time,during the system boot.
the dmesg output like : ``` [ 1.766437] in handle_fasteoi_irq for irq:7,starting... [ 1.766440] in handle_irq_event start for :7 [ 1.766440] in __handle_irq_event_percpu :7 starting...
