Ignore this rather then emitting a message or uevent. This fixes messages like these getting logged on charger unplug + replug: bq24190-charger 15-006b: Fault: boost 0, charge 1, battery 0, ntc 0 bq24190-charger 15-006b: Fault: boost 0, charge 0, battery 0, ntc 0 Cc: Tony Lindgren Cc: Hans de Goede Signed-off-by: Liam Breck Acked-by: Tony Lindgren Reviewed-by: Hans de Goede Signed-off-by: Sebastian Reichel --- diff --git a/drivers/power/supply/bq24190_charger.c b/drivers/power/supply/bq24190_charger.c index 2c404a5..59a7b6c 100644 --- a/drivers/power/supply/bq24190_charger.c +++ b/drivers/power/supply/bq24190_charger.c @@ -1222,8 +1222,13 @@ static void bq24190_check_status(struct bq24190_dev_info *bdi) } } while (f_reg && ++i < 2); + /* ignore over/under voltage fault after disconnect */ + if (f_reg == (1 << BQ24190_REG_F_CHRG_FAULT_SHIFT) && + !(ss_reg & BQ24190_REG_SS_PG_STAT_MASK)) + f_reg = 0; + if (f_reg != bdi->f_reg) { - dev_info(bdi->dev, + dev_warn(bdi->dev, "Fault: boost %d, charge %d, battery %d, ntc %d\n", !!(f_reg & BQ24190_REG_F_BOOST_FAULT_MASK), !!(f_reg & BQ24190_REG_F_CHRG_FAULT_MASK),
