Yeah I just discovered that, very useful.

But my instinct was to do:

$ ./scripts/checkkconfigsymbols.py --diff HEAD^^^..HEAD

Which didn't work, the regexp is a bit tight, fixed by:

diff --git a/scripts/checkkconfigsymbols.py b/scripts/checkkconfigsymbols.py
index a32e4da4c117..3820f00b066a 100755
--- a/scripts/checkkconfigsymbols.py
+++ b/scripts/checkkconfigsymbols.py
@@ -88,7 +88,7 @@ def parse_options():
     if args.commit and args.diff:
         sys.exit("Please specify only one option at once.")
 
-    if args.diff and not re.match(r"^[\w\-\.]+\.\.[\w\-\.]+$", args.diff):
+    if args.diff and not re.match(r"^[\w\-\.\^]+\.\.[\w\-\.\^]+$", args.diff):
