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