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.
|
||
|
|
|
||
|
|
(cherry picked from commit 5181ab917d6407cb57043e98955f0de1614366ea)
