Subject: [PATCH wireless-next v2] wl18xx: use strscpy() to instead of strncpy()
Date: Mon, 26 Dec 2022 19:14:06 +0800 (CST)	[thread overview]
Message-ID: <202212261914060599112@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.
