3.8.13.5 -stable review patch. If anyone has any objections, please let me know.
------------------
From: "Reddy, Sreekanth" <Sreekanth.Reddy@xxxxxxx>
commit b0df96a0068daee4f9c2189c29b9053eb6e46b17 upstream.
Missing delay is not getting set properly. The reason is that it is not
defined in the same file from where it is being invoked. The fix is to move
the missing delay module parameter from mpt2sas_base.c to mpt2sas_scsh.c.
