[PATCH] UBUNTU SAUCE: Mask off garbage bits provided in wmi scancodes

[Mario Limonciello]

Hi:

I'm attaching a patch that has been accepted into -mm, but I want to
make sure it's available for Karmic in case it doesn't make it in for
2.6.30 (or whatever kernel karmic ends up with).

    From: Mario Limonciello <mario_limonciello at dell.com>

    In debugging with some future machines that actually contain BIOS level
    support for dell-wmi, I've determined that the upper half of the
    data that
    comes back from wmi_get_event_data may sometimes contain extra
    information
    that isn't currently relevant when pulling scan codes out of the data.
    This causes dell-wmi to improperly respond to these events.

    Signed-off-by: Andrew Morton <akpm at linux-foundation.org>

Attaching patch so Exchange doesn't mangle it.
