Yeah, I think that disable/enable_firmware in the suspend/resume path
is basically just completely random code. There is nothing that
serializes with anything else, and it has no actual basis for saying
"I am now disabled/enabled" except for some entirely random time of
whenever the suspend/resume callbacks happen.

I'm going to revert it.

I wonder why 4.13 seemed to work for me. Or maybe it didn't, and I
just didn't notice, because I didn't use bluetooth and I wasn't
traveling. I test my laptop every release, but I don't necessarily
always _use_ it.
