If bq27000 is not I2C device it will remove line. My patch was primary
for Nokia N900 - RX51 board and it has battery bq27200 which is i2c
device. For autoloading this module I used MODULE_ALIAS("i2c:bq27200")
which works fine. Aliases was used in other i2c modules for Nokia N900
too.

Can you give me example how to use MODULE_DEVICE_TABLE (if alias is
not good solution)?
