Looks reasonable based on subsystem and the patch:
#syz fix: Bluetooth: hci_sysfs: Fix attempting to call device_add multiple times

Looks like I did add a different link when fixing it:
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=448a496f760664d3e2e79466aa1787e6abc922b5
Or perhaps they are duplicated?
