commit 33cfe0709b6bf1a7f1a16d5e8d65d003a71b6a21 upstream.
When usb_submit_urb() fails in usbio_probe(), the previously allocated
URB is never freed, causing a memory leak.
Fix this by jumping to err_free_urb label to properly release the URB
on the error path.

Add a driver for the Intel USBIO USB IO-expander used by the MIPI cameras
on various new (Meteor Lake and later) Intel laptops.
This is an USB bridge driver which adds auxbus child devices for the GPIO,
I2C and SPI functions of the USBIO chip and which exports IO-functions for
the drivers for the auxbus child devices to communicate with the USBIO
device's firmware.
