Reporting the lid status using INPUT

[Richard Hughes <hughsient@gmail.com>]

Guys,

I'm getting a few bugreports where:

* user shuts lid, initiates suspend
{lid is reported down}
* user opens lid, resume completes

But I'm not getting any lid INPUT up event. This works if you don't
initiate suspend when you shut the lid (blank screen for instance) -- so
I know my hardware is okay.

I see:

input_report_switch(input, SW_LID, !state);

in response to an event, but I'm thinking in a resume hook we should
probably do acpi_evaluate_integer(handle, "_LID", NULL, &state) and then
send an event, just so userspace is aware of what the state of the panel
is.

Does this sound sane?

Richard.
