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

[Markus Elfring <Markus.Elfring@xxxxxx>]

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”.

How do you think about to improve it?

Regards,
Markus
