That's it, right there.  Any idea how much we've bloated the kernel with
sysfs, just by insisting that the struct device not be the first item in
the struct?  There's any number of 2- and 3- line functions calling each
other, each adding and subtracting constants from the pointers passed to
them.  This was a huge mistake, IMO.
