qualcomm: Add fb notify quirk This quirk touches the `blank` file of the framebuffer /sys nodes, which ends up unsuspending things that start suspended until the right thing is happening to not be suspended. X11, among others, do the right things. It seems other framebuffer interfaces are not. This can likely be fixed in other ways, but this is the more approachable way to me right now. 2020-05-31 09:27:49 +03:00			`class Tasks::MsmFbNotify < SingletonTask`
