This demod implements an i2c adapter for attached tuner and relays i2c messages from users (dvb adapters / bridge chips). Some of them, such as Friio dvb card using gl861, require each pair of i2c messages for one read to be issued as two separate transactions. This patch adds a configuration option to enable this split.
