Some devices with an AXP288 PMIC do not have a battery at all, or use external charger and fuelgauge ICs instead of the AXP288 builtin functionality. On such devices we should not bind to the fuelgauge function to avoid exporting a non working power_supply class device. This also avoids the following errors repeating over and over again in dmesg: axp288_fuel_gauge axp288_fuel_gauge: capacity measurement not valid axp288_fuel_gauge axp288_fuel_gauge: Error 0xe2 contents not valid power_supply axp288_fuel_gauge: driver failed to report 'charge_now' property: -6 Cc: Carlo Caione <carlo@endlessm.com> Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
