Hi John,

The character device is created at the end of this pci_driver's 'probe'
routine and deleted on 'remove', so I don't think it is possible for the character device to exist prior to the 'goto', right?

JLUIII-> If the character device has been created and then the driver dies prior to the remove executing, you would be faced with an existing chardev when you restarted the driver.

Thanks,
Keith
