| |
In test_async_probe_init, second set of asynchronous devices are saved in sync_dev[sync_id], which should be async_dev[async_id]. This makes these devices not unregistered when exit.
> modprobe test_async_driver_probe && \ > modprobe -r test_async_driver_probe && \ > modprobe test_async_driver_probe ... > sysfs: cannot create duplicate filename '/devices/platform/test_async_driver.4' > kobject_add_internal failed for test_async_driver.4 with -EEXIST, don't try to register things with the same name in the same directory.
