CVE-2022-49385

In the Linux kernel, the following vulnerability has been resolved:

driver: base: fix UAF when driver_attach failed

When driver_attach(drv); failed, the driver_private will be freed.
But it has been added to the bus, which caused a UAF.

To fix it, we need to delete it from the bus when failed.
