[SCSI] libsas: prevent double completion of scmds from eh
We invoke task->task_done() to free the task in the eh case, but at this point we are prepared for scsi_eh_flush_done_q() to finish off the scmd. Introduce sas_end_task() to capture the final response status from the lldd and free the task. Also take the opportunity to kill this warning. drivers/scsi/libsas/sas_scsi_host.c: In function ‘sas_end_task’: drivers/scsi/libsas/sas_scsi_host.c:102:3: warning: case value ‘2’ not in enumerated type ‘enum exec_status’ [-Wswitch] Signed-off-by: Dan Williams <dan.j.williams@intel.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
