Hello Bartlomiej

I believe that -next commit 12de1c1ad0df
("checkpatch: add rules to check init attribute and const defects")

which adds $InitAttribute already does this test.

Anyway, this should be:
	if ($line =~ /\b(struct|union)\s+$InitAttribute.*=/) {

and please add this test adjacent to the other $InitAttribute
tests only if it's not already covered by the first bit added
by that commit below (again, I believe it is):

------------------------

# check for bad placement of section $InitAttribute (e.g.: __initdata)
		if ($line =~ /(\b$InitAttribute\b)/) {
			my $attr = $1;
			if ($line =~ /^\+\s*static\s+(?:const\s+)?(?:$attr\s+)?($NonptrTypeWithAttr)\s+(?:$attr\s+)?($Ident(?:\[[^]]*\])?)\s*[=;]/) {
