Please mention in the description of this patch that this patch does not
change any functionality because DID_OK == 0. Anyway:

Hello Johannes,

Had you noticed the following statements? I think the "<< 1" should be removed
from these statements.

$ git grep 'SAM_STAT.*<< 1'
drivers/scsi/qla2xxx/qla_isr.c:         cmd->result |= SAM_STAT_CHECK_CONDITION << 1;
drivers/scsi/qla2xxx/qla_isr.c:         cmd->result |= SAM_STAT_CHECK_CONDITION << 1;
drivers/scsi/qla2xxx/qla_isr.c:         cmd->result |= SAM_STAT_CHECK_CONDITION << 1;

Thanks,

Bart.

Thanks for the heads up, but this will be a separate patch.
