From 27a78d6a283d6782438f72306746afe4bf44c215 Mon Sep 17 00:00:00 2001 From: Anton Tikhomirov Date: Thu, 23 Feb 2012 15:38:46 +0900 Subject: [PATCH] usb: dwc3: use proper function for setting endpoint name 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.
