- * to force-load a new client at the address listed in the board info table.
- *
- * Really the I2C subsystem should have a way to force-load I2C client
- * drivers when we have a priori knowledge of what's on the bus, especially
- * since the existing I2C auto-probe mechanism is so hokey, but we'll use
