What are the additional effects? What is the end goal of converting all
the existing drivers to devm_platform_ioremap_resource? The existing

This is not an evolution, it is unnecessary churn. Those patches have no
benefit and eat up very valuable reviewer time.

There are a few other scripts that have no added value when applied to
existing code, like ptr_ret.cocci.
