Merge tag 'nfc-fixes-3.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-3.0
This is an NFC LLCP fix for 3.7 and contains only one patch.
It fixes a potential crash when receiving an LLCP HDLC frame acking a frame
that is not the last sent one. In that case we may dereference an already
freed pointer.
