What's invalid about it?  I haven't tried compiling this specific line of 
code, but I've done stuff like it in the past many times.

Are you talking about adding an integer to a void pointer?  If so, then 
that's something that gcc supports and that the kernel uses all over the 
place.  A char* is incorrect because a char could be more than one byte, 
in theory.
