Subject: kernel-doc: Not stripped #define/#ifdef/#endif in enums

Hi,
 
just noticed that #define in kernel-doc are not correctly stripped anymore from enums. Here is my patch

 
--- a/scripts/kernel-doc
+++ b/scripts/kernel-doc
@@ -1830,7 +1830,7 @@ sub dump_enum($$) {
     my $file = shift;
 
     $x =~ s@/\*.*?\*/@@gos;	# strip comments.
-    $x =~ s/^#\s*define\s+.*$//; # strip #define macros inside enums
+    $x =~ s@#\s*define\s+[^;]*;@@gos; # strip #define macros inside enums
 
     if ($x =~ /enum\s+(\w+)\s*{(.*)}/) {
 	$declaration_name = $1;

 
But there are also places in the kernel where #ifdef/#endif is used inside enums. So maybe this should also be stripped:
