Merge tag 'nfc-fixes-3.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-fixes
Samuel Ortiz <sameo@linux.intel.com> says: "This is the 2nd batch of NFC fixes for 3.9. This time we have: - A crash fix for when a DGRAM LLCP socket is listening while the NFC adapter is physically removed. - A potential double skb free when the LLCP socket receive queue is full. - A fix for properly handling multiple and consecutive LLCP connections, and not trash the socket ack log. - A build failure for the MEI microread physical layer, now that the MEI bus APIs have been merged into char-misc-next." Signed-off-by: John W. Linville <linville@tuxdriver.com>
