The story is the same as in
471cffcfb0e005b7c4044b3b52cc4f25d217efac:
device_attach() → seat_send_changed() → sd_bus_emit_properties_changed_strv()
→ emit_properties_changed_on_interface() → node_vtable_get_userdata()
→ seat_object_find(), which returns 0 because message == NULL.
But when we are emitting a signal, message is always NULL. Removing the
overeager check and assert in the called function allow the signal to be
emitted.
Fixes #13769.
int r;
assert(m);
- assert(message);
assert(ret);
if (SEAT_IS_SELF(name) || SEAT_IS_AUTO(name)) {
return -ENOMEM;
message = sd_bus_get_current_message(bus);
- if (!message)
- return 0;
r = manager_get_seat_from_creds(m, message, e, error, &seat);
if (r == -ENXIO) {
