Hirofumi Nakagawa 801678c5a3 Remove duplicated unlikely() in IS_ERR()
Some drivers have duplicated unlikely() macros.  IS_ERR() already has
unlikely() in itself.

This patch cleans up such pointless code.

James Bottomley b8e3d3aeab [SCSI] mpt fusion: fix up msi_enable in mpt_suspend
There's a problem with the combination of the upstream power
management fixes and the enabling of MSI by default in that the
suspend path still uses the global variable.  Convert it to check
ioc->msi_enable.

Michael Reed 7748369f49 [SCSI] mptsas: do not use ioc->handle to locate hba portinfo structure
While performing hardware raid reset testing via the raid's client, I
noticed that sometimes, following the reset, that there would be more
raid targets in the lsscsi output than there actually were raid
targets.  I tracked this down to the following issue.

Fusion cannot always find the mptsas_portinfo structure for the hba
because it uses the handle stored in ioc->handle to locate it.  The
problem is that the firmware can change the handle associated with the
hba when h/w raid is reset (via the raid client).  When this happens,
the driver will allocate another mptsas_portinfo structure and link it
into the chain of said structures.  This ultimately causes confusion
within the driver resulting in targets not being removed when they
should be.

Eric Moore pointed out that the hba's portinfo structure is always the
first structure on the sas_topology list.  This patch modifies
mptsas.c to access the hba's portinfo structure by taking the first
structure on said list.

come because gcc gets confused by some "goto" statements in above

function does initialize these later (after the offending goto's) in

Eric Moore e1fc2b5167 [SCSI] mptlan: bug fix, only half the message frame is dma'd resulting in corruption
NB = number of blocks.  This represents the number of blocks to
transfer.  The block size is based on the message frame size provided
in the ioc_facts. A value of zero indicates the entire message frame
should be copied. This is two bit value.  So by setting this to
non-zero vaule, you increase performance by reducing amount of data
needing to be dma'd.  The value that is stored in ioc->ReqeustNB is
sometimes a non-zero vaule, which creates a bug in mptlan, where not
the entire message frame is getting transfer to firware, resulting in
corruption.  This fix sets the default to zero, thus entire message
frame is copied.

drivers/message/fusion/mptbase.c::mpt_attach().

There are two returns that may leak the storage allocated for 'ioc'
(sizeof(MPT_ADAPTER) bytes).

A simple fix would be to simply add two kfree() calls before the return
statements, but a better fix (that this patch implements) is to reorder the
code so that if we hit the first return condition we don't have to do the
allocation at all and then just add a kfree() call for the second case.
