Subject: [RFC PATCH] platform/x86: asus-nb-wmi: Ignore unknown event 0xCF
On the Asus X541UAK an unknown event 0xCF is emited when the charger
is plugged in. This is caused by the following AML code:
If (ACPS ())
{
ACPF = One
Local0 = 0x58
If (ATKP)
{
^^^^ATKD.IANE (0xCF)
}
}
Else
{
ACPF = Zero
Local0 = 0x57
}
Notify (AC0, 0x80) // Status Change
If (ATKP)
{
^^^^ATKD.IANE (Local0)
}
Sleep (0x64)
PNOT ()
Sleep (0x0A)
NBAT (0x80)
Ignore the 0xCF event to silence the unknown event warning.
