Subject: [ 119/262] brcmfmac: fix big endian bug in i-scan.

From: Greg KH <gregkh@...uxfoundation.org>

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

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

From: Hante Meuleman <meuleman@...adcom.com>

commit ed205b361956c96e0d8c09a8c9135a6a79cd9541 upstream.

ssid len is 32 bit and needs endian conversion for big endian systems.
