drivers/message/fusion/mptctl.c: In function ‘mptctl_mpt_command’:
drivers/message/fusion/mptctl.c:1764: warning: ‘bufIn.len’ may be used uninitialized in this function
drivers/message/fusion/mptctl.c:1765: warning: ‘bufOut.len’ may be used uninitialized in this function
come because gcc gets confused by some "goto" statements in above
function. The warnings have been verified to be bogus, however, the
function does initialize these later (after the offending goto's) in
the function anyway. So let's move those initializations to top of
function, thereby also shutting up these warnings.

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.

ScsiLookup is an array of pending scmd pointers that the scsi lld
maintains. This array is touched from queuecommand, eh threads, and
interrupt context. This array should put under locks, hence this patch
to synchronize its access. I've added some nice little function
wrappers for this, and moved the ScsiLookup array over to MPT_ADAPTER
struct.

The Coverity checker spotted two potential memory leaks in
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.

If there is IO going to the volume while a hidden disk is being torn down,
there is a case where we would return a DID_NO_CONNECT for IO sent to the
volume. The end result is the volume goes read-only. This problem is due to the
fact the firmware mapped target ids saved in per device object is phys_disk_num
for hidden raid components, and target_id for the volume. There is a single
case when both phys_disk_num and target_id are equal, so enters this issue. We
fix this issue by checking the tflags when the device is torned down,
insuring the IO being completed is meant for hidden raid component, not the
volume. In addition to this fix, there are a couple other cases to address
hidden raid components. For instance task_abort and device reset are not
supported by mpt fw for hidden raid components, a bus reset would be required
or target reset to volume.

After host reset, the device are programmed to default asyn narrow nego.
We need to reprogram the parameter back to previous values. If the host
reset is called as a result of spi_dv_device() commands timing out, its
possible to get into an infinite loop of dv to host reset. This will
prevent that case, as we merely program old values. If host reset is
called outside context of domain validation, then we can call
spi_dv_device.
