Subject: [PATCH] device: Avoid calling unit_free(NULL) in device setup logic
|
|
(#4748)
|
|
|
|
Since a581e45ae8f9bb5c, there's a few function calls to
|
|
unit_new_for_name which will unit_free on failure. Prior to this commit,
|
|
a failure would result in calling unit_free with a NULL unit, and hit an
|
|
assertion failure, seen at least via device_setup_unit:
|
|
|
|
Assertion 'u' failed at src/core/unit.c:519, function unit_free(). Aborting.
|
|
|
|
Fixes #4747
|

(cherry picked from commit d112eae7da77899be245ab52aa1747d4675549f1)
