Bug Description
For machines with AMD graphic chips, it will send out WMI event and ACPI
interrupt at the same time while hitting the hotkey. BIOS will notify the
system the next display output mode throught WMI event code, so that
windows' application can show an OSD to tell the user which mode will be
taken effect. User can hit the display toggle key many times within 2
seconds to choose the mode they want. After 2 seconds, WMI dirver should
send a WMIMethod(SDSP) command to tell the BIOS which mode the user chose.
And then BIOS will raise another ACPI interrupt to tell the system to
really switch the display mode.
In Linux desktop, we don't have this kind of OSD to let users to choose
the mode they want, so we don't need to call WMIMethod(SDSP) to have
another ACPI interrupt. To simplify the problem, we just have to ignore
the WMI event, and let the first ACPI interrupt to send out the key event.
