Subject: hwmon: w83781d: Unused sysfs group w83781d_group_other

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.
What do you think?
