Christophe JAILLET 746ce6aca1 scsi: aacraid: Fix error handling paths in aac_probe_one()
[ Upstream commit f7854c382240c1686900b2f098b36430c6f5047e ]

If 'scsi_host_alloc()' or 'kcalloc()' fail, 'error' is known to be 0. Set
it explicitly to -ENOMEM before branching to the error handling path.

While at it, remove 2 useless assignments to 'error'. These values are
overwridden a few lines later.

Sagar Biradar 20d073d03b scsi: aacraid: Disabling TM path and only processing IOP reset
[ Upstream commit bef18d308a2215eff8c3411a23d7f34604ce56c3 ]

Fixes the occasional adapter panic when sg_reset is issued with -d, -t, -b
and -H flags.  Removal of command type HBA_IU_TYPE_SCSI_TM_REQ in
aac_hba_send since iu_type, request_id and fib_flags are not populated.
Device and target reset handlers are made to send TMF commands only when
reset_state is 0.

LBA, which triggers kernel panic
