net: tulip: de2104x: Checking a kmemdup() call in de21041_get_srom_info()

[Markus Elfring]

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function âde21041_get_srom_infoâ contains still an unchecked call
of the function âkmemdupâ.

https://elixir.bootlin.com/linux/v5.4-rc2/source/drivers/net/ethernet/dec/tulip/de2104x.c#L1940

How do you think about to improve it?

Regards,
Markus
