Subject: [PATCH linux-next] net: hns3: use strscpy() to instead of strncpy()
Date: Thu, 8 Dec 2022 19:53:25 +0800 (CST)	[thread overview]
Message-ID: <202212081953254923522@zte.com.cn> (raw)

From: Xu Panda <xu.panda@zte.com.cn>

The implementation of strscpy() is more robust and safer.
That's now the recommended way to copy NUL terminated strings.
