I received two identical patches (with a different title) from you.  Since there
was no explanation I will discard the first one and work with this one.

You are correct, platform_driver_register() does take care of THIS_MODULE.
Please send another revision where you will do three things:

1) CC the coresight mailing list, as instructed by get_maintainer.pl
1) Also fix the replicator driver.
2) Add a comment that clearly mentions THIS_MODULE doesn't need to be set:

                .name   = "coresight-static-funnel",
                /* THIS_MODULE is taken care of by platform_driver_register() */
                .of_match_table = static_funnel_match,
                .acpi_match_table = ACPI_PTR(static_funnel_ids),
                .pm	= &funnel_dev_pm_ops,

Thanks,
Mathieu
