commit 82afea9a87740a766e5f2683bf27b312aab95572
Author: Jody Bruchon <jody@jodybruchon.com>

     In elks/fs/romfs/inode.c, the function romfs_copyfrom() accepts
     Void *dest, but an invalid lvalue error was generated by this:

       ((char *)dest) += maxsize;

     By asking for char *dest instead, the function compiles properly.
     Since romfs is "in development," I cannot test the code, but it
     at least compiles now.
