From a5f99be41ee8d874ab63c4abf733c91a483a28d4 Mon Sep 17 00:00:00 2001 From: Miika S Date: Fri, 22 Dec 2017 17:25:31 +0200 Subject: [PATCH] input: virtio: don't send mouse wheel event twice On Linux, a mouse event is generated for both down and up when mouse wheel is used. This caused virtio_input_send() to be called twice each time the wheel was used. This commit adds a check for the button down state and only calls virtio_input_send() when it is true.
