power: supply: bq27xxx_battery: Silence deferred-probe error
The driver fails to probe with -EPROBE_DEFER if battery's power supply (charger driver) isn't ready yet and this results in a bit noisy error message in KMSG during kernel's boot up. Let's silence the harmless error message. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Reviewed-by: Andrew F.
