Subject: Re: [PATCH 6/6] ce4100: Add support for CE4100 EHCI IP block to EHCI
 driver

In a previous patch in this series GregKH asked that the PCI ID not be added 
to pci_ids.h for ID's that are only used by a single file.  
Here is an updated version of the EHCI controller patch.

Subject: [PATCH] ce4100: Add support for CE4100 EHCI IP block to EHCI driver

This patch adds support for the EHCI IP block present on the Intel
CE4100.
