Linters are still not very happy with our __init__ files, which was pointed out in recent review (see Link).

We have previously started importing things one by one to make linters happy with the test files (which import from __init__). But __init__ file itself still makes linters unhappy.

To clean it up I believe we must completely remove the wildcard imports, and assign the imported modules to __all__.

hds.py needs to be fixed because it seems to be importing the Python standard random from lib.net.

We can't use ksft_pr() / ktap_result() in case importing from net.lib fails. Linters complain that those helpers themselves may not have been imported.

Sending a fix for the driver's __init__.py first, if this is okay with everyone I'll convert the rest. I'm not super confident 'cause my Python isn't properly learned.

Sending for net, even tho its not a real fix. I think that getting it applied during the merge window may be okay? No strong prefence. I'm slightly worried that merging it in net-next after the MW will leave us with a release cycle full of merge conflicts. --- tools/testing/selftests/drivers/net/hds.py | 3 +- .../selftests/drivers/net/lib/py/__init__.py | 43 ++++++++++++++----- 2 files changed, 34 insertions(+), 12 deletions(-)
