NAME
       module_exit - driver exit entry point

SYNOPSIS
       module_exit(x);

       x
	   function to be run when driver is removed

DESCRIPTION
       module_exit will wrap the driver clean-up code with cleanup_module when used with rmmod when the driver is a module. If the driver is
       statically compiled into the kernel, module_exit has no effect. There can only be one per module.
