Input: synaptics_usb - do not rely on input_dev->users

If the device is unused and suspended, a call to open will cause the
device to autoresume through the call to usb_autopm_get_interface().

input_dev->users is already incremented by the input subsystem,
therefore this expression will always be evaluated to true:

if ((input_dev->users || (synusb->flags & SYNUSB_IO_ALWAYS)) &&
usb_submit_urb(synusb->urb, GFP_NOIO) < 0) {
retval = -EIO;
}

The same URB will then be fail when resubmitted in synusb_open().

Introduce synusb->is_open to keep track of the state instead.

Input: synaptics_usb - fix deadlock in autosuspend

usb_autopm_get_interface() that is called in synusb_open() does an

input_dev->mutex used in synusb_resume() is in this case already
taken by the input subsystem and will cause a deadlock.

Input: add INPUT_PROP_POINTING_STICK property

It is useful for userspace to know that there not dealing with a regular
mouse but rather with a pointing stick (e.g. a trackpoint) so that
userspace can e.g. automatically enable middle button scrollwheel
emulation.

It is impossible to tell the difference from the evdev info without
resorting to putting a list of device / driver names in userspace, this is
undesirable.

Add a property which allows userspace to see if a device is a pointing
stick, and set it on all the pointing stick drivers.

Input: add Synaptics USB device driver

This patch adds a driver for Synaptics USB touchpad or pointing stick
devices. These USB devices emulate an USB mouse by default, so one can
also use the usbhid driver. However, in combination with special user
space drivers this kernel driver allows one to customize the behaviour
of the device.

An extended version of this driver with support for the cPad background
display can be found at
