====================
NFC 4.3 pull request

This is the NFC pull request for 4.3.
With this one we have:

- A new driver for Samsung's S3FWRN5 NFC chipset. In order to
  properly support this driver, a few NCI core routines needed
  to be exported. Future drivers like Intel's Fields Peak will
  benefit from this.

- SPI support as a physical transport for STM st21nfcb.

- An additional netlink API for sending replies back to userspace
  from vendor commands.

- 2 small fixes for TI's trf7970a

- A few st-nci fixes.
