Subject: scsi: mpt3sas: Only one vSES is present even when IOC has multi vSES
From: Sreekanth Reddy <sreekanth.reddy@xxxxxxxxxxxx>
commit 4c51f956965120b3441cdd39c358b87daba13e19 upstream.
Whenever the driver is adding a vSES to virtual-phys list it is
reinitializing the list head. Hence those vSES devices which were added
previously are lost.
Stop reinitializing the list every time a new vSES device is added.
