SubjectRe: [PATCH RFC] scsi: ufs: Disable blk-mq for now

I don't like the per-driver switch as module_parameter at all and
we should never do that. We had some exceptions for drivers to force
blk_mq (e.g. virtio), and given that I don't think we'll solve the
blk-mq runtime-pm issue for 4.19 and also don't want to revert the
default I think this patch is the best compromise for 4.19, with
a revert in 4.20 once we have runtime-pm for blk-mq.

So:

Acked-by: Christoph Hellwig <hch@lst.de>
