[ Upstream commit e9fba20c29e27dc99e55e1c550573a114561bf8c ]
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.
