Subject: [PATCH] Introduce bus_unit_check_load_state() helper
|
|
|
1abbee |
|
|
|
1abbee |
This function is used to check that a previous unit load succeed and
|
|
|
1abbee |
returns 0 in this case.
|
|
|
1abbee |
|
|
|
1abbee |
In the case the load failed, the function setup a bus error
|
|
|
1abbee |
accordingly and returns -errno.
|
