      libata: always use polling SETXFER · 464cf177
      Tejun Heo 提交于
      Several people have reported LITE-ON LTR-48246S detection failed
      because SETXFER fails.  It seems the device raises IRQ too early after
      SETXFER.  This is controller independent.  The same problem has been
      reported for different controllers.
      
      So, now we have pata_via where the controller raises IRQ before it's
      ready after SETXFER and a device which does similar thing.  This patch
      makes libata always execute SETXFER via polling.  As this only happens
      during EH, performance impact is nil.  Setting ATA_TFLAG_POLLING is
      also moved from issue hot path to ata_dev_set_xfermode() - the only
      place where SETXFER can be issued.
      
      Note that ATA_TFLAG_POLLING applies only to drivers which implement
      SFF TF interface and use libata HSM.  More advanced controllers ignore
      the flag.  This doesn't matter for this fix as SFF TF controllers are
      the problematic ones.

      SPI dynamic busid generation bugfix · e44a45ae
      David Brownell 提交于
      Fix SPI dynamic bus ID assignment to start at 2^15-1 rather than a negative
      number.  Valid bus ids are supposed to be positive, and are (now) stored in
      an 's16' value.
