Merge tag 'nfc-next-3.7-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-3.0
So says Samuel Ortiz <sameo@linux.intel.com>: The 2nd NFC pull request for 3.7. - A couple of wrong context sleep fixes. - An LLCP rwlock intizialisation fix. - A missing mutex unlocking for pn533. - LLCP raw sockets support. This is going to be used for NFC sniffing. - A build fix for llc_shdlc. It fixes a build error triggered by code that's living in wireless-next. Signed-off-by: John W. Linville <linville@tuxdriver.com>
