Marcus Folkesson 553d16af23 Input: pegasus_notetaker - 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 (pegasus->dev->users && usb_submit_urb(pegasus->irq, GFP_NOIO) < 0)
		retval = -EIO;

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

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