[PATCH 3/6] scsi: hisi_sas: replace blk_mq_pci_map_queues with blk_mq_hctx_map_queues

From: Daniel Wagner
Date: Fri Sep 13 2024 - 03:43:43 EST


From: Daniel Wagner <dwagner@xxxxxxx>

Replace all users of blk_mq_pci_map_queues with the more generic
blk_mq_hctx_map_queues. This in preparation to retire
blk_mq_pci_map_queues.

For his_sas_v2_hw.c we have to provide its own callback for retrieving
the affinity because pci_get_blk_mq_affinity is using
pci_irq_get_affinity and not irq_data_get_affinity_mask.

But at least we can replace the open code loop with
blk_mq_hctx_map_queues.
