885ba1da68 NFC: potential integer overflow problem in check_crc() 
If "buf[0]" is 255 then "len" gets set to 0.  The call to
"crc_ccitt(0xffff, buf, len - 2);" casts the "len - 2" to a high
positive number which is ugly.

This is an NFC driver for NXP pn544.
Unlike pn544.c, this one is based on the NFC HCI and SHDLC kernel layers.
