The Coverity checker spotted the following NULL dereference:

<-- snip -->

...
static ssize_t iowarrior_write(struct file *file,
const char __user *user_buffer,
size_t count, loff_t *ppos)
{
...
if (!int_out_urb) {
retval = -ENOMEM;
dbg("%s Unable to allocate urb ", __func__);
goto error;
...
error:
usb_buffer_free(dev->udev, dev->report_size, buf,
int_out_urb->transfer_dma);
... ^^^^^^^^^^^^^^^^^^^^^^^^^

<-- snip -->
