Subject[PATCH v1] power: supply: bq27xxx_battery: Silence deferred-probe error
Date
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.
