My apologies about initially misunderstanding the fact that devm_of_iomap() behaves in a different way compared to of_iomap(). Ricardo, huge thanks for sending this revert.

This reverts commit f05c7b7d9ea9477fcc388476c6f4ade8c66d2d26. That change was causing a regression in the generic-adc-thermal-probed bootrr test as reported in the kernelci-results list [1]. A proper rework will take longer, so revert it for now.
