[Greg Kroah-Hartman]

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

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

From: Ujjal Roy <royujjal@xxxxxxxxx>

commit 517543fd72d577dde2ebd9505dc4abf26d589f9a upstream.

For IBSS join if the requested SSID matches current SSID,
it returns without freeing the allocated beacon IE buffer.
