Hi, back to this after a long context switch for some higher priority stuff.
So here I was able eventually to drop all this code and this change here https://cgit.freedesktop.org/~agrodzov/linux/commit/?h=amd-staging-drm-next-... was enough for me. Seems like while device_remove_file can handle the use case where the file and the parent directory already gone, sysfs_remove_group goes down in flames in that case due to kobj->sd being unset on device removal.

But why are things being removed twice?
Not sure I understand what removed twice ? I remove only once per sysfs attribute.
This code path shows that the kernel is trying to remove a file that is not present, so someone removed it already...
thanks,
