(I knew the other three MODULE_* macros are handled in slightly more
complicated way, but the effect is basically that they are preprocessed
away.)

Even these module macros will be pre-processed away when the driver is
statically linked (and yes, I'm not planning to ever make these driver
built as module), I'm not too sure about the convention here. I thought
that they are still good to be in the driver for information purpose.
I'm seeing other pinctrl drivers doing this as well.

Maybe Linus can help to clarify this?

As pointed out in another mail on similar subject, I think these macros
are a kind of obsolete documentation and if they should be dropped we
need to go over an entire subsystem at a time and remove all boolean users
in a big patch.
