3.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Cong Ding <ding...@gmail.com>
commit 10b8c7dff5d3633b69e77f57d404dab54ead3787 upstream.
When it goes to error through line 144, the memory allocated to *devname is
not freed, and the caller doesn't free it either in line 250. So we free the
memroy of *devname in function cifs_compose_mount_options() when it goes to
error.
