FROMGIT: scsi: ufs: Use DBD setting in mode sense UFS standard requires DBD field to be set to 1 in MODE SENSE(10). Some card vendors are more strict and check the DBD field, hence respond with CHECK_CONDITION (Sense key set to ILLEGAL_REQUEST and ASC set to INVALID FIELD IN CDB). When host sends MODE SENSE for page caching, as a result of the CHECK_CONDITION response, host assumes that the device doesn't support the cache feature and doesn't send SYNCHRONIZE_CACHE commands to flush the device cache. This can result in data corruption in case of sudden power down when there is data stored in the device cache. This patch fixes the DBD field setting as required in UFS standard.
