[PATCH] staging: gdm72xx: fix leaks at failure path in gdm_usb_probe()

From: Alexey Khoroshilov
Date: Wed Feb 05 2014 - 19:47:32 EST


Error handling code in gdm_usb_probe() misses to deallocate
tx_ and rx_structs and to do usb_put_dev().

Found by Linux Driver Verification project (linuxtesting.org).
