Hello, w83781d.c contains a definition of sysfs group: static const struct attribute_group w83781d_group_other = { .attrs = w83781d_attributes_other, }; the only usage of which is: static void w83781d_remove_files(struct device *dev) { ... sysfs_remove_group(&dev->kobj, &w83781d_group_other); } So, it seems the group should be either created in w83781d_create_files() or removed completely.
