Subject: [PATCH] scsi: mpt3sas: change _base_get_msix_index prototype
References: bsc#1125703,jsc#SLE-4717
Git-commit: 0213651609b91180d1645388d35d6e77d7e0a886
Patch-mainline: v5.3-rc1
Code refactoring.
In function _base_get_msix_index, add scmd as second argument. This change
is made in preparation for the next patch where we introduce a new function
to get the MSI-X index for high iops queues.
