I went on to apply the series, however CI detected a regression in the
unit tests:

https://source.denx.de/u-boot/custodians/u-boot-dfu/-/jobs/764396

This can be reproduced with:
$ ./test/py/test.py --bd sandbox --build -k ut_hush_hush_test_simple_dollar

I've narrowed this down to:
 [PATCH v6 5/6] lib: membuff: fix readline not returning line in case of overflow

Could you please have a look?

Thank you!
