[PATCH] VT binding: Update fbcon to support binding
The control for binding/unbinding is moved from fbcon to the console layer. Thus the fbcon sysfs attributes, attach and detach, are also gone. 1. Add a notifier event that tells fbcon if a framebuffer driver has been unregistered. If no registered driver remains, fbcon will unregister itself from the console layer. 2. Replaced calls to give_up_console() with unregister_con_driver(). 3. Still use take_over_console() instead of register_con_driver() to maintain compatibility 4. Respect the parameter first_fb_vc and last_fb_vc instead of using 0 and MAX_NR_CONSOLES - 1. These parameters are settable by the user. 5. When fbcon is completely unbound from the console layer, fbcon will also release (iow, decrement module reference counts to zero) all fbdev drivers. In other words, a bind or unbind request from the console layer will propagate down to the framebuffer drivers. 6. If fbcon is not bound to the console, it will ignore all notifier events (except driver registration and unregistration) and all sysfs requests.
