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> --- drivers/power/supply/bq27xxx_battery.c | 5 ++++- 1 file changed, 4 insertions(+), 1 deletion(-)
