Hans de Goede 2848e039c5 power: supply: Make power_supply_am_i_supplied return -ENODEV if there are no suppliers ... It is sensible to assume that the hardware actually always has a way of charging the battery so when power_supply_am_i_supplied does not find any suppliers, that does not mean that there are none, but simply that no power_supply-drivers are registered / bound for any suppliers for the supply calling power_supply_am_i_supplied. At which point a fuel-gauge driver calling power_supply_am_i_supplied() cannot determine whether the battery is being charged or not. Allow a caller of power_supply_am_i_supplied to differentiate between there not being any suppliers, vs no suppliers being online by returning -ENODEV if there are no suppliers matching supplied_to / supplied_from, which allows fuel-gauge drivers to return POWER_SUPPLY_STATUS_UNKNOWN rather then POWER_SUPPLY_STATUS_DISCHARGING if there are no suppliers.
