Have you been able to reproduce this? Do you think there is enough information to reproduce the bug and/or solve? If not, be sure to let me know what you need. Known workarounds, if existing, would also be welcomed. Thanks in advance!
This seems to me to be a fairly trivial issue to fix. So I am personally adding a 30usd bounty for anyone who fixes this in a good way (needs to go upstream). Preferably with a test-case. If this is not trivial, please say so.
Created attachment 28772 [details] [review] 0001-Reset-local-private-to-NULL-after-freeing-it.-22693.patch Can you test this patch please. Seems to be a bug that affects some other input drivers too.

I can confirm that this patch solves the issue. I've experienced one crash upon unplugging, but do not know the reason for this or have been able to reproduce. Will update or file a new bug if this happens again and I can find which component that seems to be at fault.
