Re: [PATCH] hptiop: HighPoint RocketRAID 3xxx controller driver

[HighPoint Linux Team <linux@highpoint-tech.com>]

Updates:
- don't bypass SYNCHRONIZE_CACHE command
- return SCSI_MLQUEUE_HOST_BUSY when no free request slots
- move scsi_remove_host() to the begin of hpt_remove(), or it will
  not work after resources being released.
