I suggest to take another look at the commit 7945f929f1a77a1c8887a97ca07f87626858ff42
("drivers: provide devm_platform_ioremap_resource()" from 2019-02-20)
which triggered the discussed software evolution.

> What is the end goal of converting all the existing drivers to devm_platform_ioremap_resource?

It was accepted by well-known Linux developers to put two function calls
into another wrapper function.

I am curious if other contributors would like to describe more variants
of software development opinions in affected areas.

Would you like to clarify concerns around such source code transformation
approaches in more detail?
