3.16.79-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: Navid Emamdoost <navid.emamdoost@xxxxxxxxx>
commit db8fd2cde93227e566a412cf53173ffa227998bc upstream.
In mwifiex_pcie_alloc_cmdrsp_buf, a new skb is allocated which should be
released if mwifiex_map_pci_memory() fails. The release is added.
Fixes: fc3314609047 ("mwifiex: use pci_alloc/free_consistent APIs for PCIe")
