Vincent Mailhol a1ad2109ce can: etas_es58x: fix potential NULL pointer dereference on udev->serial 
The driver assumed that es58x_dev->udev->serial could never be NULL.
While this is true on commercially available devices, an attacker
could spoof the device identity providing a NULL USB serial number.
That would trigger a NULL pointer dereference.

Add a check on es58x_dev->udev->serial before accessing it.
