Nothing wrong with this, but in looking at the definition of
container_of(), I see this:

 * WARNING: any const qualifier of @ptr is lost.
 * Do not use container_of() in new code.

And there's now container_of_const(), where I see this:

 * Always prefer container_of_const() instead of container_of() in new code.
