[PATCH 0/1] gpiolib-acpi: make sure we trigger edge events at least once

[Hans de Goede <hdegoede@xxxxxxxxxx>]

Hi All,

I'm back from Guadec so now I've had a chance to test that this patch
indeed fixes the USB MUX not muxing the right controller at boot and it
does.

As discussed, this patch adds an initial event handler run to get things in
sync with the boot status of the GPIO input-pin generating the events.

New in this non RFC version is delaying the initial run. My testing has
shown that we need to delay the initial run, to give other drivers a chance
to register their OperationRegions first. This is unfortunate, but not
really a problem. Since the firmware does not do this initial sync itself
things (e.g. the USB MUX) will already be in the wrong state for many
seconds (e.g. as long as the bootloader menus is shown). So a couple
of seconds more should not be a problem.

Regards,

Hans
