staging: wlan-ng: Checking a kmemdup() call in prism2sta_inf_hostscanresults()

[Markus Elfring]

Hello,

I have tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function âprism2sta_inf_hostscanresultsâ contains still
an unchecked call of the function âkmemdupâ.

https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/staging/wlan-ng/prism2sta.c#L1086

How do you think about to improve it?

Regards,
Markus
