* unbind_con_driver - unbind a console driver
* @csw: pointer to console driver to unregister
* @first: first in range of consoles that @csw should be unbound from
* @last: last in range of consoles that @csw should be unbound from
* @deflt: should next bound console driver be default after @csw is unbound?
*
* To unbind a driver from all possible consoles, pass 0 as @first and
* %MAX_NR_CONSOLES as @last.
*
* @deflt controls whether the console that ends up replacing @csw should be
* the default console.
*
* RETURNS:
* -ENODEV if @csw isn't a registered console driver or can't be unregistered
* or 0 on success.
