Some BIOS versions/Vaio models apparently ship with two nearly identical
functions to handle backlight related controls.
The only difference seems to be:
If (LEqual (BUF1, 0x40))
{
Store (0x40, P80H)
Store (BUF2, Local0)
- And (Local0, One, Local0)
+ And (Local0, 0x03, Local0)
Store (Local0, ^^H_EC.KLPC)
}
Avoid erroring out on initialization and messing things up on cleanup
for now since we never call into these methods with anything different
than 1 or 0.
This issue was found on a Sony VPCSE1V9E/BIOS R2087H4.
