Subject[PATCH 4.10 109/167] can: usb_8dev: Fix memory leak of priv->cmd_msg_buffer
Date
4.10-stable review patch.  If anyone has any objections, please let me know.

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

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

commit 7c42631376306fb3f34d51fda546b50a9b6dd6ec upstream.

The priv->cmd_msg_buffer is allocated in the probe function, but never
kfree()ed. This patch converts the kzalloc() to resource-managed
kzalloc.
