Indeed the #ifdef's have probably been used to keep the difference
to the original Linux kernel source minimal.
Before they are removed, one should test how difficult it is to
update code as is against current Linux mainline, maybe by rebasing
against or cherry-pickin from there. I have no idea how much code
has checnged in both driver versions since, and how difficult any
such upgrade might be, but we should check it.

If its just for reading / understanding the code, you can always run
it through the unifdef tool ...

Real programmers don't comment their code. It was hard to write, it
should be hard to understand.
