Hi,
This follows the discussion here: https://lore.kernel.org/linux-kselftest/20230324123157.bbwvfq4gsxnlnfwb@houa...
This shows a couple of inconsistencies with regard to how device-managed resources are cleaned up. Basically, devm resources will only be cleaned up if the device is attached to a bus and bound to a driver. Failing any of these cases, a call to device_unregister will not end up in the devm resources being released.
We had to work around it in DRM to provide helpers to create a device for kunit tests, but the current discussion around creating similar, generic, helpers for kunit resumed interest in fixing this.
This can be tested using the command: ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/base/test/
Let me know what you think, Maxime

Is there any news on this?
Can you resend, last I saw the kernel test robot had a problem, which causes any patch series like that to be ignored by me.
thanks,
