Merge tag 'isci-for-3.6' into for-next
isci update for 3.6
1/ Fix the workaround for drives that have a slow response to COMSAS.
Drives with this problem intermittently take a long time to be
identified, or fail to be identified altogether.
2/ A minor fix for the efi variable code failure path
3/ A handful of smatch fixups from Dan Carpenter
