Oh, indeed. Thanks for spotting this.

The 'owner' is set by core for platform drivers as well. Most platform
drivers were already converted (I think by Wolfram Sang). I extended
existing coccinelle script to fix also i2c_drivers and sometimes did not
notice that it was platform_driver.

I can split it into two different patches. Would that be ok?

Best regards,
Krzysztof
