Subject: [PATCH 17/44] input: make LoCoMo keyboard driver support both poodle
and collie
Keyboards on collie and poodle differ only in wiring of 'Home' key.
Instead of complicating the driver with platform data, just check for
the machine for the time being. This will be converted to DTS property
sometime in the future.
