So could you describe a bit what the issue you are trying to fix?

This is host level runtime PM you are trying to address, and if blk-mq
runtime isn't enabled, I guess the host won't be runtime suspended at all
because some of its descendant are always active.

So seems we need to do nothing for preventing the host controller from
entering runtime suspend.

Thanks,
