Subject: [PATCH] scsi: megaraid_sas: Re-use max_mfi_cmds to calculate queue
Git-commit: 9fb98561164a9a9ec4d906313dccf3807f6ad035
Patch-mainline: v5.0-rc1
References: FATE#325920
 sizes

In megasas_init_adapter_fusion(), max_mfi_cmds is being calcuated as
(MEGASAS_FUSION_INTERNAL_CMDS + MEGASAS_FUSION_IOCTL_CMDS).  max_mfi_cmds
can be used in megasas_configure_queue_sizes.
