Subject: Input: vmmouse - fix absolute device registration
From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>
commit d4f1b06d685d11ebdaccf11c0db1cb3c78736862 upstream.
We should set device's capabilities first, and then register it,
otherwise various handlers already present in the kernel will not be
able to connect to the device.
