Input: vmmouse - fix absolute device registration
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. Reported-by: Lauri Kasanen <cand@gmx.com> Cc: stable@vger.kernel.org Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
