From: Ricardo Cañuelo <ricardo.canuelo@collabora.com>

commit 86edac7d3888c715fe3a81bd61f3617ecfe2e1dd upstream.

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.
