    Pre-probe the device (eventcomm only). · 05e22a58

    For auto-dev, we'd probe the device node and get the axis ranges. If we
    specify the device however we didn't retrieve the axis ranges and thus got
    stuck with the defaults - losing out on automatic edge and accel calculation.
    This is an issue if the device is hotplugged, as HAL will specify the device
    This patch adds another hook to synproto_operations to pre-probe the device.
    This hook is only used by eventcomm and opens the FD, queries the axis range
    and closes the FD again.
