From 1105a13bb8ad29cf83d46989ee462d196038be87 Mon Sep 17 00:00:00 2001 From: Alexey Khoroshilov Date: Fri, 14 Jun 2013 00:26:11 +0400 Subject: [PATCH] orinoco_usb: fix memory leak in ezusb_access_ltv() when device disconnected If "device is disconnected" check occurs to be true in ezusb_access_ltv(), it just return -ENODEV. But that means request_context is leaked since there are no any references to it anymore. The patch adds a call to ezusb_request_context_put() before return.
