Re: [PATCH AUTOSEL 4.19 04/22] drm/vc4: crtc: Use an union to store the page flip callback

Hi!

From: Maxime Ripard maxime@cerno.tech

[ Upstream commit 2523e9dcc3be91bf9fdc0d1e542557ca00bbef42 ]

We'll need to extend the vc4_async_flip_state structure to rely on another callback implementation, so let's move the current one into a union.

This and [04/22] drm/vc4: crtc: Use an union to store the page flip callback is queued for 4.9 / 4.19, preparing for change that is not queued into 4.19.

Please drop at least from 4.9 and 4.19.

Best regards, Pavel
