      scsi: megaraid_sas: Fix data integrity failure for JBOD (passthrough) 
devices
      
      [ Upstream commit 1e793f6fc0db920400574211c48f9157a37e3945 ]
      
      Commit 02b01e010afe ("megaraid_sas: return sync cache call with
      success") modified the driver to successfully complete SYNCHRONIZE_CACHE
      commands without passing them to the controller. Disk drive caches are
      only explicitly managed by controller firmware when operating in RAID
      mode. So this commit effectively disabled writeback cache flushing for
      any drives used in JBOD mode, leading to data integrity failures.

      scsi: megaraid_sas: Fix data integrity failure for JBOD (passthrough) 
devices
      
      [ Upstream commit 1e793f6fc0db920400574211c48f9157a37e3945 ]
      
      Commit 02b01e010afe ("megaraid_sas: return sync cache call with
      success") modified the driver to successfully complete SYNCHRONIZE_CACHE
      commands without passing them to the controller. Disk drive caches are
      only explicitly managed by controller firmware when operating in RAID
      mode. So this commit effectively disabled writeback cache flushing for
      any drives used in JBOD mode, leading to data integrity failures.
