Subject: SUNRPC: Checking a kmemdup() call in xdr_netobj_dup()

Hello,

I tried another script for the semantic patch language out.
This source code analysis approach points out that the implementation
of the function “xdr_netobj_dup” contains still an unchecked call
of the function “kmemdup”.
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/include/linux/sunrpc/xdr.h?id=1c0cc5f1ae5ee5a6913704c0d75a6e99604ee30a#n167
https://elixir.bootlin.com/linux/v5.4-rc2/source/include/linux/sunrpc/xdr.h#L167

How do you think about to improve it?

Regards,
Markus
