You can resend, but I believe there are a few more instances
of this that might need fixing too.

I don't have perl 5.22 so it's difficult for me to test.

Here's a grep with some possible false positives
and maybe missing some too.

$ git grep -n "=[\!~].*{" scripts/checkpatch.pl|grep -vw qr|grep -vP '{$|{\s*#|\${|\\{|{[\d$]'
scripts/checkpatch.pl:1143:				$remainder =~ /^(else)(?:\s|{)/ &&
scripts/checkpatch.pl:1233:	$stmt =~ s/^\s*{//;
scripts/checkpatch.pl:2458:				if ($file =~ m{^(.*?)(?::\d+)+:?$} &&
scripts/checkpatch.pl:2802:		if ($line =~ /^\+(.*)\(\s*$Type\s*\)([ \t]++)((?![={]|\\$|$Attribute|__attribute__))/ &&
scripts/checkpatch.pl:3015:			$s =~ s/{.*$//s;
scripts/checkpatch.pl:3168:			$s =~ s/^\s*{//;
scripts/checkpatch.pl:3274:		if ($line =~ /^.\s*{/ &&
scripts/checkpatch.pl:3282:				$fixedline =~ s/\s*=\s*$/ = {/;
scripts/checkpatch.pl:3285:				$fixedline =~ s/^(.\s*){\s*/$1/;
scripts/checkpatch.pl:3606:		if (($line=~/$Type\s*$Ident\(.*\).*\s*{/) and
scripts/checkpatch.pl:3613:				$fixed_line =~ /(^..*$Type\s*$Ident\(.*\)\s*){(.*)$/;
scripts/checkpatch.pl:3625:		if ($line =~ /^.\s*{/ &&
scripts/checkpatch.pl:3635:				$fixedline =~ s/^(.\s*){\s*/$1\t/;
scripts/checkpatch.pl:4104:## 		if ($line =~ /^.\s*$Type\s+$Ident(?:\s*=[^,{]*)?\s*,\s*$Ident.*/ &&
scripts/checkpatch.pl:4124:				$fixed[$fixlinenr] =~ s/^(\+.*(?:do|\))){/$1 {/;
scripts/checkpatch.pl:4734:					$seen++ if ($block =~ /^\s*{/);
