Michael Zaidman 1edfae51d5 HID: ft260: support i2c writes larger than HID report size ... To support longer than one HID report size write, the driver splits a single i2c message data payload into multiple i2c messages of HID report size. However, it does not replicate the offset bytes within the EEPROM chip in every consequent HID report because it is not and should not be aware of the EEPROM type. It breaks the i2c write message integrity and causes the EEPROM device not to acknowledge the second HID report keeping the i2c bus busy until the ft260 controller reports failure. This patch preserves the i2c write message integrity by manipulating the i2c flag bits across multiple HID reports to be seen by the EEPROM device as a single i2c write transfer.
