asus-wmi: Create quirk for airplane_mode LED
[ Upstream commit a977e59c0c67c9d492bb16677ce66d67cae0ebd8 ]
Some Asus laptops that have an airplane-mode indicator LED, also have
the WMI WLAN user bit set, and the following bits in their DSDT:
Scope (_SB)
{
(...)
Device (ATKD)
{
(...)
Method (WMNB, 3, Serialized)
{
(...)
If (LEqual (IIA0, 0x00010002))
{
OWGD (IIA1)
Return (One)
}
}
}
}
So when asus-wmi uses ASUS_WMI_DEVID_WLAN_LED (0x00010002) to store the
wlan state, it drives the airplane-mode indicator LED (through the call
to OWGD) in an inverted fashion: the LED is ON when airplane mode is OFF
(since wlan is ON), and vice-versa.
This commit creates a quirk to not register a RFKill switch at all for
these laptops, to allow the asus-wireless driver to drive the airplane
mode LED correctly through the ASHS ACPI device. It also adds a match to
that quirk for the Asus X555UB, which is affected by this problem.
