Subject: [PATCH net-next] ath5k: use strscpy() to instead of strncpy()
Date: Fri, 23 Dec 2022 10:34:45 +0800 (CST)	[thread overview]
Message-ID: <202212231034450492161@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.
