Subject: [PATCH v4 00/10] blk: refactor queue affinity helpers
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.

Changes in v4:
- added irq_get_affinity callback to struct device_driver
- hisi_sas use dev pointer directly from hisi_hba.
- blk_mq_hctx_map_queues: ty irq_get_affinity callback
from device_driver first then from bus_type
- collected tags
- fixed typos
- Link to v3: https://lore.kernel.org/r/20241112-refactor-blk-affinity-helpers-v3-0-573bfca0cbd8@kernel.org
Changes in v3:
- dropped the additinal argument in blk_mq_hctx_map_queues.
leave open coded version in hisi_sas_v2.
- splitted "blk-mp: introduce blk_mq_hctx_map_queues" patch into
three patches.
- dropped local variable in pci_device_irq_get_affinity
- Link to v2: https://lore.kernel.org/r/20241111-refactor-blk-affinity-helpers-v2-0-f360ddad231a@kernel.org
Changes in v2:
- added new callback to struct bus_type and call directly the affinity
helpers from there.
- Link to v1: https://lore.kernel.org/r/20240913-refactor-blk-affinity-helpers-v1-0-8e058f77af12@suse.de
Changes in v1:
- renamed blk_mq_dev_map_queues to blk_mq_hctx_map_queues
- squased 'virito: add APIs for retrieving vq affinity' into
'blk-mq: introduce blk_mq_hctx_map_queues'
- moved hisi_sas changed into a new patch
- hisi_sas use define instead of hard coded value
- moved helpers into their matching subsystem, removed
blk-mq-pci and blk-mq-virtio files
- fix spelling/typos
- fixed long lines in docu (yep new lines in brief descriptions are
supported, tested ti)
- based on the first part of
[1] https://lore.kernel.org/all/20240806-isolcpus-io-queues-v3-0-da0eecfeaf8b@suse.de
