The core DSA framework uses hsr_is_master() which would not resolve to a
valid symbol if HSR is built-into the kernel and DSA is a module.

I had initially considered making is_hsr_master() a static inline that
would compare dev->dev.type->name with "hsr" since the HSR master would
set a custom dev_type, however the xrs700x driver would still fail to
link because it calls hsr_get_version() and for that one there is no
easy solution.

Thanks for looking into this. It's not something I've run into before.
It didn't occur to me what would happen if HSR was a module. I'll look
out for this in the future.
Sorry for the inconvenience.
