[ Upstream commit ec61f0bb4feec3345626a2b93b970b6719743997 ]
Some Alienware devices have a key that locks/unlocks the Meta key. This key triggers a WMI event that should be ignored by the kernel, as it's handled by internally the firmware.
There is no known way of changing this default behavior. The firmware would lock/unlock the Meta key, regardless of how the event is handled.
Tested on an Alienware x15 R1.
