Fuzzing is dynamic analysis, so I'm not sure how that fits.

syzbot (a real fuzzer -- I believe it uses fake USB devices [1])
caught the error, apparently:
so you might look at using that too.

Traditionally, "testing your patches" means having hardware that runs
the driver in question when patching said driver. That likely won't
scale for researchers, but then, perhaps it just means you need to be
more clear on how you caught the issue and how you did (or didn't)
test it, so it's easier to reconcile your claims with the testing done
by real users.

If you only did static analysis, then we can be more confident in
reverting. The fuzz-tested revert is an even nicer bonus.
