Driver drivers/hwmon/pcf8591.ko declares and removes attribute group pcf8591_attr_group_opt, but it does not create it ever. Is it better to remove it completely or to do something else?
Do nothing. Look closely at the file instead to see how the attributes are created, and realize that the group is only used to simplify attribute removal. Yes, the code is a bit odd and unusual, but it is WAI. Guenter
