+Fix it and free non-matching devices.

+Subject: [PATCH] libudev: enumerate: fix NULL-deref for subsystem-matches
+
+udev_device_get_subsystem() may return NULL if no subsystem could be
+figured out by libudev. This might be due to OOM or if the device
+disconnected between the udev_device_new() call and
+udev_device_get_subsystem(). Therefore, we need to handle subsystem==NULL
+safely.
+
+Instead of testing for it in each helper, we treat subsystem==NULL as
+empty subsystem in match_subsystem().
+
+Backtrace of udev_enumerate with an input-device disconnecting in exactly
+this time-frame:
