There's already a generic implementation so use that instead.

I'm not sure if the driver usage of atomic_or?() is correct in terms of
storage size of @val for 64 bit arches.

Assuming LP64 programming model for linux on say x86_64: atomic_or()
callers in this driver use long (sana 64 bit) storage and pass it to
atomic_orr/atomic_or which downcasts it to 32 bits. Is that OK ?

What's the plan with this patch? Should I take it to my
wireless-drivers-next tree or will someone else take it?


Per last discussion on this topic, Arend wanted to discuss abt this with Hante.
I'm not taking it anyways so feel free to pick it up if you want !

Well, that was before your "timeline" clarification about the generic function. One what tree is this patch based?

Regards,
Arend
