      [SCSI] pmcraid: Fix ppc64 driver build for using cpu_to_le32 on U8 data type · 88197966
      Anil Ravindranath authored
      Fix a reported ppc64 driver build issue. Removed cpu_to_le32 conversion
      usage for flags in struct pmcraid_ioadl_desc. This was breaking the driver build in ppc64.
      
      drivers/scsi/pmcraid.c: In function 'pmcraid_request_sense':
      drivers/scsi/pmcraid.c:2254: warning: large integer implicitly truncated
      to unsigned type

      [SCSI] scsi_transport_fc: Fix WARN message for FC passthru failure paths · 61ec33eb
      Brian King authored
      There are three error paths in the FC passthru code where
      job->reply->reply_payload_rcv_len does not get initialized,
      resulting in the WARN_ON in fc_bsg_jobdone going off. This patch
      fixes this. An example of one of the WARN_ON messages seen:
