The software combination “Coccinelle 1.3.0” does also not produce an expected
difference display by the following SmPL script variant according to the
implementation of the function “tilcdc_crtc_create”.
https://elixir.bootlin.com/linux/v6.17-rc7/source/drivers/gpu/drm/tilcdc/tilcdc_crtc.c#L1017-L1076


@badarg2@
position p, q, r;
expression devm, e, local;
@@
*devm =@p devm_kzalloc(...);
 ...
*local =@r <+... devm ...+>;
 ...
*drm_crtc_init_with_planes(@q e, <+... local ...+>, ...)


How will the software be improved further?

Regards,
Markus
