0d04df9b4a [SCSI] mpt2sas : fix oops when firmware sends large sense buffer size
There is a bug in firmware where the reply message frame says there is a
16kb sense buffer, when in reality its only 20 bytes.  This fix insures
the memcpy action doesn't corrupte the memory beyond the 90 bytes allocated in
the scsi command for sense buffer.

ba33fadfab [SCSI] mpt2sas: make global symbols unique
The ioc_list global symbol is already used in 1st generation mpt
fusion drivers, so this patch makes it unique in the 2nd generation
driver.  I've checked the entire sources, and I don't see any other
global system missing the mpt2sas_xxx prefix.
