The commit (especially the subject) should be more descriptive, it's not that we're missing error checks it's that you're handling garbage passed in from the user a bit more gracefully.
I'm not sure how useful this is as-is - if you're not checking your errors you're not checking your errors so it's probably just pushing the robustness failures around, especially since...

...this is too quiet, this should at the very least be generating a loud warning so people can see there's a problem (probably with WARN_ON so we can see what called it). Can you respin with something noisier please?
Also NULL is a valid regulator (though we don't use it right now). [unhandled content-type:application/pgp-signature] | |
