Subject: [PATCH net-next] brcm80211: use strscpy() to instead of strncpy()
Date: Fri, 23 Dec 2022 10:37:21 +0800 (CST)	[thread overview]
Message-ID: <202212231037210142246@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.
