[PATCH] HID, hid-picolcd: Fix memory leak inpicolcd_debug_out_report()

From: Jesper Juhl
Date: Sun Jan 02 2011 - 16:17:19 EST


Hi,

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.
