Igor Pylypiv d712d3fb48 scsi: pm80xx: Fix TMF task completion race condition ... The TMF timeout timer may trigger at the same time when the response from a controller is being handled. When this happens the SAS task may get freed before the response processing is finished. Fix this by calling complete() only when SAS_TASK_STATE_DONE is not set. A similar race condition was fixed in commit b90cd6f2b9 ("scsi: libsas: fix a race condition when smp task timeout") Link: https://lore.kernel.org/r/20210707185945.35559-1-ipylypiv@google.com Reviewed-by: Vishakha Channapattan <vishakhavc@google.com> Acked-by: Jack Wang <jinpu.wang@ionos.com> Signed-off-by: Igor Pylypiv <ipylypiv@google.com> Signed-off-by: Martin K.
