6.11-stable review patch. If anyone has any objections, please let me know.
------------------
From: Daniel Wagner <dwagner@xxxxxxx>
[ Upstream commit a141c17a543332fc1238eb5cba562bfc66879126 ]
blk_mq_pci_map_queues() maps all queues but right after this, we overwrite
these mappings by calling blk_mq_map_queues(). Just use one helper but not
both.
Fixes: 42f22fe36d51 ("scsi: pm8001: Expose hardware queues for pm80xx")
