Description
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().
