CVE-2025-40116

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

usb: host: max3421-hcd: Fix error pointer dereference in probe cleanup

The kthread_run() function returns error pointers so the
max3421_hcd->spi_thread pointer can be either error pointers or NULL.
Check for both before dereferencing it.
