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.
