Hello Wolfram,
I noticed that module autoload won't be working in some of the i2c
busses drivers. This patch series contains the fixes for these.
Best regards,
Javier

If the driver is built as a module, autoload won't work because the module
alias information is not filled. So user-space can't match the registered
device with the corresponding module.
Export the module alias information using the MODULE_DEVICE_TABLE() macro.
