Convert `dvobj_to_dev` macro into static inline function,
because it is not great to have macro that use `container_of` macro,
because from looking at the definition one cannot tell what type it applies to.
One can get the same benefit from an efficiency point of view by making an
inline function (concretely, typically a static inline function, because
the definition only needs to be visible in the current file, or in the
case of a header file in the file that includes the header file).

How have you chosen the names at the beginning of the subject line? The
other patches on this file don't have the word "include:" in the subject.
Please see the section "Following the Driver commit style" of the tutorial
to see what to do.

But the message is a bit too verbose. Please see my suggestion on another
similar patch that was recently proposed.
