no, wrong. when run : echo out > direction,
dmesg say :
one mistake in #165,
```but there's no data``` is some copy/past err.

};
enum gpiod_flags {
GPIOD_ASIS = 0,
GPIOD_IN= GPIOD_FLA
according to the above analysis, error is happen with the direction is :
in
i found the function to set the direction of gpio pin to in:
amd_gpio_direction_input,
and add some pr_err and dump_stack() to the function ,
then dmesg out put like :
[1.545190] amd_gpio_set_config
gpio_chip->la
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_ev
so may be there is some bug with the :direction,
because ,i run echo out > direction,then it start to work.
and may be just like #130 or #133 ,but in drivers related to this
touchpad .
