From 0d45d79de22feb4f32de08249e93d878fa6fdab8 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 25 May 2018 21:50:37 +0300 Subject: [PATCH] drm/vmwgfx: Stop using plane->fb in atomic_enable() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Instead of looking at the (soon to be deprecated) plane->fb we'll examing plane->state->fb instead. We can do this because vmw_du_crtc_atomic_check() prevents us from enabling a crtc without the primary plane also being enabled. Due to that same reason, I'm actually not sure what the checks here are for NULL fb. If we can't enable the crtc without an enabled plane we should always have an fb. But I'll leave that for someone else to figure out.
