Otherwise we lose the ability to enumerate I2C devices from ACPI namespace on some distros (at least Debian builds I2C core as a module).

Actually there's a patch that moves DT I2C helpers to the I2C core here: https://lkml.org/lkml/2013/8/19/349 we should probably do the same for the ACPI case. Doing that solves this problem as well. -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
