    Subject[PATCH 4.4 054/105] scsi: lpfc: Fix crash during Hardware error recovery on SLI3 adapters
    Date
    4.4-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: James Smart <jsmart2021@gmail.com>


    [ Upstream commit 5d181531bc6169e19a02a27d202cf0e982db9d0e ]

    if REG_VPI fails, the driver was incorrectly issuing INIT_VFI
    (a SLI4 command) on a SLI3 adapter.
