Re: [PATCH] x86: powernow-k8: ignore out-of-range PstateStatus value

[Ingo Molnar <mingo@elte.hu>]

nice fix! A few minor nits:

Please use the customary comment style:

  /*
   * Comment .....
   * ...... goes here:
   */

and since it's multi-line anyway, keep to the 80-col limit too please.

Any reason why it has been moved to a separate line? (either split all 
fields or keep them all together)

Please use an enum, not a define in the middle of a struct.

Thanks,
