* slowly or not at all and still power rest of the system from
* USB. This allows one for example to keep battery at its recommended
* storage capacity of 40% without having to physically remove the
* battery.
*
* Note that kernel will round the limit to nearest suitable value
* which is usually a few milliamperes lower than the supplied limit.
*
* Also note that changing usb charger limit will reset also this
* battery charger limit to the same value so you must first set usb
* charger limit and only then battery charger limit.
*
* Returns 0 on success and negative value on failure.
