device will not inherit state from the previous user. It can also be
used to execute delayed power switching state changes, e.g. in
- conjunction with the vga-switcheroo infrastructure. Beyond that KMS
+ conjunction with the vga_switcheroo infrastructure. Beyond that KMS
drivers should not do any further cleanup. Only legacy UMS drivers might
need to clean up device state so that the vga console or an independent
fbdev driver could take over.
