Subject: usb: dwc3: use proper function for setting endpoint name
From: Anton Tikhomirov <[email protected]>
commit 27a78d6a283d6782438f72306746afe4bf44c215 upstream.
It's wrong to use the size of array as an argument for strncat.
Memory corruption is possible. strlcat is exactly what we need here.
