ACPI: Ignore _BQC object when registering backlight device
upstream commmit: c2c789057f075022658b38b498755c29c1ba8055
According to acpi spec , the objectes of _BCL and _BCM are required if
integrated LCD is present and supports brightness level and the _BQC is
the optional object. So the _BQC object will be ignored when the backlight
device is registered.
At the same time when there is no _BQC object, the current brightness will be
set to the maximum.
