Hi there,

Sorry for the late reply.

The patch works, however, I added a couple lines in order to make it work
on my laptop:

In toshiba_acpi_query_event:
       status = execute_acpi_method(toshiba_acpi.acpi_dev->handle, "INFO",
				    NULL, hotkey);

Here, the handle should be the ACPI device, not the EC

In toshiba_acpi_add:
	/* enable hotkey event */
	hci_write1(HCI_HOTKEY_EVENT, 1, &hci_result);

My model (and a couple others) the ENAB method is empty, and hotkey
activation is done via HCI_HOTKEY_EVENT


Another thing that I've noticed is that "device->device_type" is always zero
for me, I thought that it was supposed to be 1, due to  {"TOS1900", 1}.
So I changed the comparison value to 0 in order to get the hotkeys
reported.


Saludos
Azael
