I do not think so, I was able to build and load the driver with these
changes. It looks like this enum is used as a type of the state parameter of
ddk750_set_dpms function, but the three defined constants are never referenced. 
Should we get rid of dpms enum and change the type of the parameter to an unsigned integer?
