Applied to https://git.kernel.org/pub/scm/linux/kernel/git/hid/hid.git (for-6.8/upstream-fixes), thanks!

[1/3] HID: bpf: remove double fdget()
      https://git.kernel.org/hid/hid/c/7cdd2108903a
[2/3] HID: bpf: actually free hdev memory after attaching a HID-BPF program
      https://git.kernel.org/hid/hid/c/89be8aa5b0ec
[3/3] HID: bpf: use __bpf_kfunc instead of noinline
      https://git.kernel.org/hid/hid/c/764ad6b02777
