Yup, that one might be a bit aggressive.
It's a complaint about function pointer declaration style.
from checkpatch:
------------------------------------------------------
# unnecessary space "type (*funcptr)(args...)"
elsif ($declare =~ /\s{2,}$/) {
WARN("SPACING",
"Multiple spaces after return type\n" . $herecurr);
}
------------------------------------------------------
This is warning about style equivalent to declarations like:
int foo(int bar);
checkpatch doesn't warn about declarations of that style,
so likely checkpatch shouldn't warn about multiple spaces
after a function pointer return type either.
I don't have a strong opinion one way or another about it.
If you think it should be silenced, it could be either
downgraded to a CHK or removed altogether.
