Subject: [PATCH] HID: asus: Prevent Claymore sending suspend event
Date: Sat, 7 Aug 2021 14:49:21 +1200
Message-Id: <20210807024921.26479-1-luke@ljones.dev>
List-ID: <linux-input.vger.kernel.org>
X-Mailing-List: linux-input@vger.kernel.org
Prevent the ASUS Claymore keyboard from sending a suspend event
when the device sleeps itself. The suspend event causes a system
suspend if uncaught.
