Original description

In the SPI library's DigitalPotControl control example, the digitalPotWrite() function is defined to return an int, but there is no return value at the end of the function. The calling code doesn't use the return value, but as a proper example, the digitalPotWrite() function should have a return value if it's defined to return an int, or should be changed to void.
