Subject: EEPROM: fix checksum for FT230X series
X-Git-Url: http://developer.intra2net.com/git/?p=libftdi;a=commitdiff_plain;h=0fad6f389a7cad0513b23f73b2439700e53d47b3

EEPROM: fix checksum for FT230X series

ftdi_eeprom_build() computes the checksum via reading the "Factory
Configuration Data" region. ftdi_eeprom_decode() computes the checksum
only on the EEPROM buffer. Hence, both checksums differ.

Add the info from "Factory Configuration Data" to the EEPROM buffer.
