power: supply: bq24190_charger: Limit over/under voltage fault logging
If the charger is unplugged before the battery is full we may see an over/under voltage fault. 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 <tony@atomide.com> Cc: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Liam Breck <kernel@networkimprov.net> Acked-by: Tony Lindgren <tony@atomide.com> Reviewed-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
