Yes, sure. In fact we would like to do that, the same comment was given 
by other reviewers. But when we looked at some other examples present in 
the same file (mode_property, edid_property), they have created a 
wrapper function around this, in the same file. So just followed the 
convention, but if that can be done, we will do it in the next patch set.
