Subject: [PATCH net-next] wl18xx: use strscpy() to instead of strncpy()

From: Xu Panda <[email protected]>

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

Wireless patches go to wireless-next, not net-next. Also always Cc
linux-wireless list, more info in the wiki link below.
