According to responses from the BIOS team, ASUS_WMI_METHODID_DSTS2
(0x53545344) will be used as future DSTS ID. In addition, calling
asus_wmi_evaluate_method(ASUS_WMI_METHODID_DSTS2, 0, 0, NULL) returns
ASUS_WMI_UNSUPPORTED_METHOD in new ASUS laptop PCs. This patch fixes
no DSTS ID will be assigned in this case.

None of the drivers implementing the ACPI device suspend callback
uses the pm_message_t argument of it, so this argument may be dropped
entirely from that callback.  This will simplify switching the ACPI
bus type to PM handling based on struct dev_pm_ops.

As this has never worked, better to blacklist the driver for now.

The interface just doesn't work on some machines, and Dell haven't been

Acer Extensa 5235, TravelMate 5760 and Aspire 5750 laptop have broken _BCM
implemenation, the AML code wrote value to EC register but firmware didn't
change brighenss.

Fortunately, the brightness control works on those machines with vendor mode.
So, add this machine to video backlight vendor mode quirk table.
