      libata: fix hotplug for drivers which don't implement LPM · eb0e85e3
      Tejun Heo 提交于
      ata_eh_analyze_serror() suppresses hotplug notifications if LPM is
      being used because LPM generates spurious hotplug events.  It compared
      whether link->lpm_policy was different from ATA_LPM_MAX_POWER to
      determine whether LPM is enabled; however, this is incorrect as for
      drivers which don't implement LPM, lpm_policy is always
      ATA_LPM_UNKNOWN.  This disabled hotplug detection for all drivers
      which don't implement LPM.
      
      Fix it by comparing whether lpm_policy is greater than
      ATA_LPM_MAX_POWER.
