Hi,

Thank you so much for help.

I am not using the last snapshot of Linux, but the 2.6.23 release.
My source code is not completly up-to-date.

For example there is no reference of I2C_BOARD_INFO in board-h4.
I have no 'i2c_device_id menelaus_id[]' in the i2c drivers code.

Perhap's that's why I am quite confuse, I am refering to recent code examples
and I am using not-so-recent Linux version.


In the documentation, "New-style" drivers are presented very quickly.
In fact, I still don't know where must be located the valid client list:
- in the board init source code with I2C_BOARD_INFO() macro
- in the i2c driver source code

With my Linux version, i2c_device_id list was not present in the i2c_driver
structure. So i2c_board_info is supposed to match with what ?

Cool :)
Lines removed !
