I don't care about this one patch, it's fine.  But generally and for
future reference, we don't try very hard to use a consistent style
within a driver.  The preference is almost always kernel style over
driver style so new code should always be "kernel style" where
we avoid casting from kmalloc() or other functions that return void
pointers.
