These two hooks should be optional. The only downside of not adding them is that zpos property can't be read, everything else should still work ... And yeah everyone added zpos without a hole lot of thought about cross-driver consistency, which is not great. Now everyone gets to clean things up again I'd say. -Daniel <div><div class="h5"> > > Benjamin > > > 2016-01-07 14:50 GMT+01:00 Daniel Vetter <<a href="mailto:daniel@ffwll.ch">daniel@ffwll.ch</a>>: > > > On Thu, Jan 07, 2016 at 02:30:38PM +0100, Benjamin Gaignard wrote: > > > Without those function zpos property isn't displayed in atomic mode. > > > > > > Signed-off-by: Benjamin Gaignard <<a href="mailto:benjamin.gaignard@linaro.org">benjamin.gaignard@linaro.org</a>> > > > > Oh, another iteration of a driver-private zpos property.
