to improve code maintainability. This follows the kernel coding style
recommendation for memory allocations.

The build bot reply already shows that you did not even build test
the patch. :(

This change is completely unrelated to the rest of the patch
and not described, aside from being broken. The macro is clearly
confusing, so if you want to imprve this, I would suggest removing
it and instead open-coding the contents.

When you do this type of change, you have to check that the
types are actually the same. The original code makes sense,
your change is broken because 'private_data' as usual refers to
a opaque pointer.
