Aaron Lu a50188dae3 acpi: video: enhance the quirk detect logic of _BQC ... Currently we decide if the _BQC is using index by first setting the level to maximum, and then check if _BQC returned maximum; if not, we say it is using index. This is not true for some buggy systems, where the _BQC method will always return a constant value(e.g. 0 or 100 for the two broken system) and thus break the current logic. So this patch tries to enhance the quirk detect logic for _BQC: we do this by picking a test_level, it can be the maximum level or the mininum one based on some condition. And we don't make the assumption that if _BQC returned a value that is not what we just set, it must be using an index. Instead, we will compare the value returned from _BQC and if it doesn't match, see if the returned value is an index. And if still no, clear the capability of _BQC.
