[PATCH 5.4 172/367] driver core: test_async: fix an error code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


5.4-stable review patch.  If anyone has any objections, please let me know.


From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

[ Upstream commit 22d2381bbd70a5853c2ee77522f4965139672db9 ]

The test_platform_device_register_node() function should return error
pointers instead of NULL.  That is what the callers are expecting.

Fixes: 57ea974fb871 ("driver core: Rewrite test_async_driver_probe to cover serialization and NUMA affinity")
