Subject: [PATCH v4 0/3] HID: hidraw: HIDIOCREVOKE introduction

The is the v4 of the HIDIOCREVOKE patches.

Link to v3: https://lore.kernel.org/all/20240812052753.GA478917@quokka/

After a small discussion with Peter, we decided to:
- drop the BPF hooks that are problematic (Linus doesn't want
  "ALLOW_ERROR_INJECTION" to be used as "normal" fmodret bpf hooks)
- punt those BPF hooks later once we get the API right
- I'll be the one sending that new version, given that it's easier for
  me ATM

For testing the patch, and for convenience, I added a new selftest
program that can test this new ioctl. This will also allow us to
integrate the (future) BPF hooks and show how this should be used.
