This is inserting lots of duplicate and control heavy code.
It looks like the same pattern and is using just platform_xxx funxtions.

Any counter-examples with a different pattern, which you converted in
a different manner?

Wouldn't it be more useful to do these checks in 
platform_register_simple() and return the proper error value there?

Or just create a small helper, if this have to be done seperate.

Greg, what do you think here?
