driver core: Fix test_async_probe_init saves device in wrong array
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. Fixes: 57ea974fb871 ("driver core: Rewrite test_async_driver_probe to cover serialization and NUMA affinity") Signed-off-by: Chen Zhongjin <chenzhongjin@huawei.com> Link: https://lore.kernel.org/r/20221125063541.241328-1-chenzhongjin@huawei.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
