This is a well-motivated 7-patch series from Bartosz Golaszewski fixing a software node leak in the platform device subsystem: when a software node is passed via `struct platform_device_info`, it is not removed on device `.release()`, causing a `-EBUSY` on reuse. The overall approach — convert affected drivers, add a new helper, then fix the core — is sound.
However, **two of the driver-conversion patches (1/7 and 4/7) have bugs in the cleanup/unregister paths** that would cause use-after-free or use-of-uninitialized-value issues. These need to be fixed before the series can land.
The core platform changes (patches 2, 3, 5) and the kunit additions (patches 6, 7) look correct.
