It seems this series broke the CI when testing sandbox:
https://source.denx.de/u-boot/custodians/u-boot-dfu/-/jobs/1349214

Can you have a look please?

This can be reproduced locally using:

$ ./test/py/test.py --bd sandbox --build -k test_bind
[...]
FAILED test/py/tests/test_bind.py::test_bind_unbind_with_node - AssertionError: assert 'Unable to bind. err:0' == ''
FAILED test/py/tests/test_bind.py::test_bind_unbind_with_uclass - AssertionError: assert 2 == 1
