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

gpib: Fix memory leak in ni usb init()

In ni usb init(), if ni usb setup init() fails, the function returns -EFAULT without freeing the allocated writes buffer, leading to a memory leak.

Additionally, ni usb setup init() returns 0 on failure, which causes ni usb init() to return -EFAULT, an inappropriate error code for this situation.

Fix the leak by freeing writes in the error path. Modify ni usb setup init() to return -EINVAL on failure and propagate this error code in ni usb init().
