Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function =E2=80=9Cltq_pinctrl_dt_subnode_to_map=E2=80=9D contains s=
till
two unchecked calls of the function =E2=80=9Ckmemdup=E2=80=9D.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/dr=
ivers/pinctrl/pinctrl-lantiq.c?id=3D1c0cc5f1ae5ee5a6913704c0d75a6e99604ee3=
0a#n116
https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/gpu/drm/nouveau/n=
ouveau_connector.c#L476

How do you think about to improve it?

Regards,
Markus
