      ACPI / Battery: Return -ENODEV for unknown values in get_property() · a1b4bd69
      Rafael J. Wysocki 提交于
      The function acpi_battery_get_property() is called by the
      power supply framework's function power_supply_show_property()
      implementing the sysfs interface for power supply devices as the
      ACPI battery driver's ->get_property() callback.  Thus it is supposed
      to return error code if the value of the given property is unknown.
      Unfortunately, however, it returns 0 in those cases and puts a
      wrong (negative) value into the intval field of the
      union power_supply_propval object provided by
      power_supply_show_property().  In consequence, wrong negative
      values are read by user space from the battery's sysfs files.
      
      Fix this by making acpi_battery_get_property() return -ENODEV
      for properties with unknown values (-ENODEV is returned, because
      power_supply_uevent() returns with error for any other error code
      returned by power_supply_show_property()).
