* dell-wmi: don't generate errors on empty messagesMatthew Garrett2009-06-17
| | | | | | | | | There's no point in generating kernel messages if we didn't receive a parsable keyboard event - only do so if there appeared to be a scancode.

* dell-wmi: mask off upper bytes of event responseMario Limonciello2009-06-17
| | | | | | | | | | | | | 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.

* dell-wmi: new driver for hotkey controlMatthew Garrett2009-04-03
Add a WMI driver for Dell laptops. Currently it does nothing but send a generic input event when a button with a picture of a battery on it is pressed, but maybe other uses will appear over time.
