Subject: pinctrl: lantiq: Checking two kmemdup() calls in
 ltq_pinctrl_dt_subnode_to_map()

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “ltq_pinctrl_dt_subnode_to_map” contains still
two unchecked calls of the function “kmemdup”.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pinctrl/pinctrl-lantiq.c?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n116
https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/gpu/drm/nouveau/nouveau_connector.c#L476

How do you think about to improve it?

Regards,
Markus
