I'll try to take a look later. For Logic PD distributions, we create
a custom defconfig with all those drivers removed, so I'm not worked
up about it, but it would be nice to not call drivers that don't
exist.

Thanks for reviewing this. I've been coping for a while by manually
changing the config option, but with 5.4 being the expected next LTS,
I was hoping to address this so I don't have to keep working around
it.

I'll send out a second e-mail with some of your suggestions, but I
don't want to litter this e-mail with too many logs.
