Pull IPMI updates from Corey Minyard:
 "Bug fixes for main IPMI driver, kcs updates

  A couple of bug fixes for the main IPMI driver, one functional and two
  annotations.

  The kcs driver has some significant updates that have been pending for
  a while, but I forgot to include in next until a week ago. But this
  code is only used by the people who are sending it to me, really, so
  it's not a big deal. I did want it to sit in next for at least a week,
  and it did result in a fix"

+# Aspeed KCS (Keyboard Controller Style) IPMI interface
 
 The Aspeed SOCs (AST2400 and AST2500) are commonly used as BMCs
 (Baseboard Management Controllers) and the KCS interface can be
 used to perform in-band IPMI communication with their host.
