Merge tag 'nfc-fixes-3.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/nfc-fixes 



Samuel Ortiz <sameo@linux.intel.com> says:

'This is the second NFC fixes pull request for 3.11.

We have:

- A build failure fix for the NCI SPI transport layer due to a
  missing CRC_CCITT Kconfig dependency.

- A netlink command rename: CMD_FW_UPLOAD was merged during the 3.11
  merge window but the typical terminology for loading a firmware to a
  target is firmware download rather than upload. In order to avoid any
  confusion in a file exported to userspace, we rename this command into
  CMD_FW_DOWNLOAD."
