Are you sure of this line ?
Because when I add this line next to it :
	printk(KERN_INFO "RJK: charge_gpio = %d\n", pdata->charge_gpio);
I get :
[  160.079239] power_supply mioa701_battery: prop VOLTAGE_NOW=4012
[  160.089767] power_supply mioa701_battery: prop VOLTAGE_MAX=4032
[  160.099772] power_supply mioa701_battery: prop VOLTAGE_MIN=3072
[  160.111776] RJK: charge_gpio = 260440062

Needless to say that my kernel doesn't boot in that case (because of the
following gpio_get_value()). I was expecting to have "-1" in my printk.

Cheers.
