Subject: [PATCH 1/1] x86/platform: classmate-laptop: Add cmpc_keys support for new classmate laptops

The cmpc_keys ACPI driver from the classmate-laptop module fails to
recognize the device on the 4th generation of classmate laptops (Atom N450)
because the device ID is named "FNBT0000" (uppercase N) on this laptops.

MODALIAS=acpi:FNBT0000:

This patch makes the driver cmpc_keys recognize it:

input: cmpc_keys as /devices/LNXSYSTM:00/device:00/FNBT0000:00/input/input18
