Subject: [PATCH 3.18 11/32] can: gs_usb: fix memory leak in gs_cmd_reset()

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marc Kleine-Budde <mkl@...gutronix.de>

commit 5cda3ee5138e91ac369ed9d0b55eab0dab077686 upstream.

This patch adds the missing kfree() in gs_cmd_reset() to free the
memory that is not used anymore after usb_control_msg().
