From: Marc Kleine-Budde <mkl@xxxxxxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
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.
