[SCSI] ipr: Module parm to disable RAID 0 auto create
Some ipr adapters will automatically create single device RAID 0 arrays for all unconfigured RAID capable devices found at adapter initialization time. This patch adds a module parameter to disable this behavior. Signed-off-by: Brian King <brking@us.ibm.com> Signed-off-by: James Bottomley <James.Bottomley@SteelEye.com>
