I finally bisected a acpi video regression on my aspire 5720G

Reverting commit 

"ACPI video: support _BQC/_BCL/_BCM methods that use index values"
commit 1a7c618a3f7bef1a20ae740df512eeba21397fa5.

Makes it work, otherwise /sys/class/backlight is empty, and I get error
messages when I press hardware keys to change brightness:

"ACPI: Failed to switch the brightness"

Best regards,
	Maxim Levitsky
