[PATCH net-next v3] NFC: s3fwrn5: Replace strcpy() with strscpy()
Posted by tomasz.unger@yahoo.pl 1 month, 1 week ago
From: Tomasz Unger <tomasz.unger@yahoo.pl>

Replace strcpy() with strscpy() which limits the copy to the size of
the destination buffer. Since fw_info->fw_name is an array with a
fixed, declared size, the two-argument variant of strscpy() is used -
the compiler deduces the buffer size automatically.

This is a defensive cleanup replacing the deprecated strcpy()
with the preferred strscpy().
