From 0fbf8ed976af5bb43cf9cf2492161eb9688fee0c Mon Sep 17 00:00:00 2001 From: Jesper Juhl Date: Sun, 2 Jan 2011 22:17:00 +0100 Subject: [PATCH] HID: hid-picolcd: Fix memory leak in picolcd_debug_out_report() We have a memory leak in drivers/hid/hid-picolcd.c::picolcd_debug_out_report() in an error path.. We are not always freeing the memory allocated to 'buff' - this patch makes sure we always kfree() what we allocate with kmalloc() when it is no longer needed.
