I propose to take another closer look at a bit of SmPL code.

I have got an other software development view here.

I agree to this information.

Please check once more.

=E2=80=A6
+@search exists@
+local idexpression id;
+expression x,e,e1;
+position p1,p2;
=E2=80=A6
+@@
+
+id =3D of_find_device_by_node@p1(x)
+... when !=3D e =3D id
=E2=80=A6

Or:

=E2=80=A6
+ ... when !=3D id =3D e
=E2=80=A6


Which SmPL specification will achieve the desired software behaviour?
