    [PATCH] fbdev state management · f8048030
    Benjamin Herrenschmidt authored
    This adds some "state" information for power management to fbdev's,
    along with a notifier mecanism to inform clients of state changes.  It
    also "uses" this mecanism in the function fb_set_suspend() which was an
    empty placeholder previously, and "shields" various places that access
    the HW when state isn't running.  (It's best to not call them in the
    first place, but the current state of fbcon makes that _very_ difficult)
