Subject: [PATCH net-next] wifi: atmel: use strscpy() to instead of strncpy()
Date: Fri, 23 Dec 2022 10:54:55 +0800 (CST) [thread overview]
Message-ID: <202212231054555312754@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.
