From 8f25229026c89912574558d0a4e36c8fe51b9bb4 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Fri, 19 Aug 2011 11:00:55 +0300 Subject: HID: hid-lg4ff: add a kfree() to an error path There is a small rare potential memory leak here. Also Walter Harms points out that we can do a small cleanup as well by using kstrdup().
