[PATCH 4/4] IPMI: Add proper offset for HP PCI interfaces

[Corey Minyard]

From: Corey Minyard <cminyard@xxxxxxxxxx>

On a PCI update, the offset for HP PCI interfaces to the IPMI controller
was left off.  Add the offset back in.  The "dead code" dealing with
first_reg_offset was removed in 2.6.32, so that is re-added.
