Hmm... well that's annoying! I just attempted to merge this set, but
early build tests fail due to a dependency already merged into -next.

../drivers/mfd/rave-sp.c:227:25: error:
implicit declaration of function ‘crc_ccitt_false’

We need to figure out if either of the following are true:

- Patch [0] can be dropped from Andrew's tree
- ... and I can take it via the MFD tree instead
- Patch [0] is on an immutable branch I can pull in to my PR

If not, it will have to wait until the next cycle.

lib/crc-ccitt: add CCITT-FALSE CRC16 variant

In support of a soon to be published MFD driver using serdev to talk to
a supervisory processor that uses the CCITT-FALSE CRC16 variant in it's
protocol, this patch was tested successfully on an i.MX6 ARM platform.
