Ick, no, why?  What is wrong with removing this function as is?  Don't
mark something as __depreciated if there are no in-kernel users, just
delete it and move on.

If you have out-of-tree drivers, then yes, they can make a wrapper for
this function like this if they really feel the need, or they can get
their code merged :)
