Sorry for not being clear. I simply meant you could write the following:

define WM831X_VOLTAGE(id, name) \
	static SENSOR_DEVICE_ATTR(in##id##_input, S_IRUGO, show_voltage, \
				  NULL, name)

#define WM831X_NAMED_VOLTAGE(id, name) \
	WM831X_VOLTAGE(id, name);					\
	static SENSOR_DEVICE_ATTR(in##id##_label, S_IRUGO, show_label,	\
				  NULL, name)

Which makes it more obvious that WM831X_NAMED_VOLTAGE is WM831X_VOLTAGE
+ label. But it's really up to you which way you prefer.
