From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>
INIT_DELAYED_WORK() takes two arguments: A pointer to the delayed work and
a function reference for the callback.
The rtl code casts all function references to (void *) because the
callbacks in use are not matching the required function signature. That's
error prone and bad pratice.
Some of the callback functions are also global, but only used in a single
file.
Clean the mess up by:
- Adding the proper arguments to the callback functions and using them in
the container_of() constructs correctly which removes the hideous
container_of_dwork_rtl() macro as well.
- Removing the type cast at the initializers
- Making the unnecessary global functions static
