From 95c060869e6872ea03a4a9d15236adcffb1d8b07 Mon Sep 17 00:00:00 2001 From: Shivasharan S Date: Fri, 10 Feb 2017 00:59:23 -0800 Subject: scsi: megaraid_sas: latest controller OCR capability from FW before sending shutdown DCMD Fetch the latest controller OCR capability from FW before sending MR_DCMD_CTRL_SHUTDOWN When application sends a shutdown DCMD (MR_DCMD_CTRL_SHUTDOWN), driver will fetch latest controller information from firmware. This is to ensure that driver always has latest OCR capability of controller before sending the DCMD.
