Hi, 

apologies for the delay in this reviews...

Nice hardening work, Sashiko complains about a few unrelated things (of
course :P), there is only probably a good point around the update of
DEBUG_COUNTERS that you added


https://sashiko.dev/#/patchset/20260814-scmi-async-done-race-v1-0-335b163d77ee%40rivian.com

"Will this new counter actually increment for timed-out responses, or will it 
be blocked by earlier validation logic?"

I mean please consider if you can improve the patch only regarding the
DEBUG_COUNTER update (probably moving the update where async_done is now
set to NULL is enough...)

Beside this, look good to me and in my testing everything was fine.

Thanks
Cristian
