A recent commit added barry support to this driver, but that causes a link failure when CONFIG_POWER_SUPPLY is not set: drivers/hid/built-in.o: In function `hidpp_battery_get_property': :(.text+0x1a834): undefined reference to `power_supply_get_drvdata' drivers/hid/built-in.o: In function `hidpp_raw_event': :(.text+0x1b10c): undefined reference to `power_supply_changed' drivers/hid/built-in.o: In function `hidpp_connect_event': :(.text+0x1bd88): undefined reference to `devm_power_supply_register' :(.text+0x1be30): undefined reference to `power_supply_powers' This adds a dependency, identically to the other HID drivers that need this.
