Subject: scsi: mpi3mr: Return I/Os to an unrecoverable HBA with DID_ERROR
Git-commit: 256bd4f23d9cecaba2e6795f0058fa9c2362698c
Patch-mainline: v5.19-rc1
References: jsc#PED-1446
Complete all new I/O requests issued to an unrecoverable controller with
DID_ERROR status instead of returning the I/O requests with
SCSI_MLQUEUE_HOST_BUSY. This will prevent the infinite retries of the new
I/Os when a controller is in an unrecoverable state.
