Baes on Johns' idea, I added another irq_get_affinity callback to struct device_driver and made blk_mq_hctx_map_queues to try that one first. With this I could also replace the open coded queue mapping in hisi_sas v2. Besides this change I fixed couple of typos and also addressed John feedback in hisi_sas v3. Original cover letter: These patches were part of 'honor isolcpus configuration' [1] series. To simplify the review process I decided to send this as separate series because I think it's a nice cleanup independent of the isolcpus feature.
