[TRIVIAL] [Trivial Patch] scsi_register-004

[Rusty Trivial Russell <rusty@rustcorp.com.au>]

From:  Michael Still <mikal@stillhq.com>

  
  This patch has been generated as part of my scsi_register audit of the 2.5.45 kernel tree. scsi_register() can fail, returning a NULL pointer, and the failure case was not being handled here...
