platform/x86: asus-wmi: try to set als by default
some laptops, for example ASUS UX330UAK, have brocken als_get function
but working als_set funktion. In this case, ALS will stay turned off.
Method (WMNB, 3, Serialized)
{
...
If (Local0 == 0x53545344)
{
...
If (IIA0 == 0x00050001)
{
If (!ALSP)
{
Return (0x02)
}
Local0 = (GALS & 0x10) <<<---- bug,
should be: (GALS () & 0x10)
If (Local0)
{
Return (0x00050001)
}
Else
{
Return (0x00050000)
}
}
.....
If (Local0 == 0x53564544)
{
...
If (IIA0 == 0x00050001)
{
Return (ALSC (IIA1))
}
......
Method (GALS, 0, NotSerialized)
{
Local0 = Zero
Local0 |= 0x20
If (ALAE)
{
Local0 |= 0x10
}
Local1 = 0x0A
Local1 <<= 0x08
Local0 |= Local1
Return (Local0)
}
Since it works without problems on Windows I assume ASUS WMI driver for Win
never trying to get ALS state, and instead it is setting it by default to ON.
This patch will do the same. Turn ALS on by default.
