Subject: [PATCH resend] thermal: int3400_thermal: Ignore charger events
Date: Wed, 14 Feb 2018 16:13:40 +0100	[thread overview]
Message-ID: <20180214151340.1811-2-hdegoede@redhat.com> (raw)
In-Reply-To: <20180214151340.1811-1-hdegoede@redhat.com>

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]
