Subject: [PATCH linux-next.git] irq: irq and pci_ids patch for additional Intel Cougar Point DeviceIDs

This patch adds additional LPC Controller DeviceIDs for the Intel Cougar Point PCH.

The DeviceIDs are defined and referenced as a range of values, the same way Ibex Peak was implemented.

This patch was built against the linux-next.git tree.

Signed-off-by: Seth Heasley <seth.heasley@...el.com>
