Subject: [PATCH] udev/path_id: correct segmentation fault due to missing NULL
803fb7
 check
803fb7
803fb7
Running "udevadm test-builtin path_id /sys/devices/platform/" results
803fb7
in a segmentation fault.
803fb7
803fb7
The problem is that udev_device_get_subsystem(dev) might return NULL
803fb7
in a streq() call.  Solve this problem by using streq_ptr() instead.
