Hi,

+static void virtinput_cfg_abs(struct virtio_input *vi, int abs)
+{
+	u32 mi, ma, re, fu, fl;
+
+	virtinput_cfg_select(vi, VIRTIO_INPUT_CFG_ABS_INFO, abs);
+	virtio_cread(vi->vdev, struct virtio_input_config, u.abs.min, &mi);
+	virtio_cread(vi->vdev, struct virtio_input_config, u.abs.max, &ma);
+	virtio_cread(vi->vdev, struct virtio_input_config, u.abs.res, &re);
+	virtio_cread(vi->vdev, struct virtio_input_config, u.abs.fuzz, &fu);
+	virtio_cread(vi->vdev, struct virtio_input_config, u.abs.flat, &fl);
+	input_set_abs_params(vi->idev, abs, mi, ma, fu, fl);
+	input_abs_set_res(vi->idev, abs, re);
+}

+struct virtio_input_absinfo {
+	__virtio32  min;
+	__virtio32  max;
+	__virtio32  fuzz;
+	__virtio32  flat;
+	__virtio32  res;
+};

Damn, had sparse disabled for the test builds.  [ Too bad there are way
too many warnings on a full kernel build so having sparse enabled all
the time doesn't fly. ]

So this doesn't work either.

Hmm, back to using "u32" in the virtio config structs?

cheers,
