I did catch that while compiling with clang, and the exact error message
is:
drivers/net/ethernet/cirrus/cs89x0.c:1899:21: warning: attribute
declaration must precede definition [-Wignored-attributes]
static const struct __maybe_unused of_device_id cs89x0_match[] = {

That seems not to fire when compiling with clang. I guess because the
attribute is after the _complete_ type?

Same here...

Afaik, "struct of_device_id" as a whole is a type. This case is really
odd since it puts the attribute in the middle of a type. It is the only
instance which came across (not everything compiles fine with clang yet,
so there might be more... but a quick grep did not turn up more of the
same cases)...

Given that, can you reconsider?
