Better then previous one.

But my version of bq27xxx_battery.c already contains this:

static const struct kernel_param_ops param_ops_poll_interval = {
        .get = param_get_uint,
        .set = poll_interval_param_set,
};

...so it should be possible to set poll interval already.

This is for allowing udev rule to set the properties as well.
otherwise a kinda crude RUN = " echo value >
/sys/module/bq27xxx_battery/parameters/poll_interval" is required.
