Hi Krzysztof,
Thank you for the patch.

The following change would also work, as the of_match_table field of
struct device_driver isn't conditioned by CONFIG_OF:

Your patch should reduce the module size without any real drawback as
far as I can see, so that's probably best. I'm fine with either
approach, so
