Hi Alec,

Thanks, that all sounds good -- if mine lands first, great; the wrapper
split is exactly as you describe, so rebasing 3/3 is just relocating your
report-check hunk.

On the NULL msc->input deref: good timing -- I actually already have a fix
for that one ready, from digging into the same Sashiko review on your
series. Rather than a guard in the callbacks, I went at the root cause in
magicmouse_probe(): the USB Magic Mouse 2 / Trackpad 2 path returns 0
before the existing "input not registered" check, so I moved that check
ahead of the early return. That rejects a device that bound without an
input and covers both ->raw_event and ->event in one go.

I just sent it as a separate patch so we don't duplicate -- happy for you
to review, and shout if you'd rather take it instead.

Thanks,
Jose
