Hi All,

This patch seems to have fallen through the cracks, hence this resend.

[PATCH resend] thermal: int3400_thermal: Ignore charger events

[Hans de Goede]

Ignore events of type 0x86 which are fired of when plugging in / out the
charger, judging from both observed behavior and the AML code on an Asus
T100HA.

This silences these kernel errors on the T100HA:
[   86.599918] acpi INT3400:00: Unsupported event [0x86]
[  120.133024] acpi INT3400:00: Unsupported event [0x86]

I think the problem can be covered by this commit, right?

    thermal: int3400_thermal: Ignore Unknown Notification Codes
    
    Some BIOS implementations route ACPI codes other than 0x83 to
INT3400
    device. Ignore these ACPI notification codes because the INT3400
driver
    does not handle them.
