2009-12-10[SCSI] pm8001: Fix for sata io circular lock dependency.jack wang1-5/+35
This patch fix for sata IO circular lock dependency. When we call task_done for SATA IO, we have got pm8001_ha->lock ,and in sas_ata_task_done, it will get (dev->sata_dev.ap->lock. then cause circular lock dependency .So we should drop pm8001_ha->lock when we call task_done for SATA task.
