* sos: don't change NBITS.NIIBE Yutaka2020-05-041-2/+0
| | | | | | | | | | | For SOS, an ECC point with prefix 0x40 can be represented in two ways. One for 0x40 interpreted as 7-bit, another as 8-bit (MSB is zero). This matters for fingerprint computation, so, the representation should be preserved, or we should use another flag to hold the difference in the representation...
