Subject: [PATCH 4/4] HID: multitouch: Disable event reporting on suspend when the device is not a wakeup-source
Date: Sat, 29 May 2021 17:14:24 +0200	[thread overview]
Message-ID: <20210529151424.12212-5-hdegoede@redhat.com> (raw)
In-Reply-To: <20210529151424.12212-1-hdegoede@redhat.com>

Disable event reporting on suspend when the hid device is not
a wakeup-source. This should help save some extra power in this case.
