This series fixes stale vblank timestamps in the first event sent after a crtc was disabled. The core now is notified via drm_crtc_vblank_off before sending the last pending event in atomic_disable. If the crtc is reenabled right away during to a modeset, the event is not sent at all, as the next vblank will take care of it. -----BEGIN PGP SIGNATURE----- iI0EABYIADUWIQRRO6F6WdpH1R0vGibVhaclGDdiwAUCXR3UqxcccC56YWJlbEBw ZW5ndXRyb25peC5kZQAKCRDVhaclGDdiwFogAQCE6HPaBbBOHJBT5hU4ysJG1Qge GuS/OKB2ZUDyrf3a1wEAy1qa+49x68a2coFksD571VDf+Pm85mRk+NrKl1oFFQo= =Bs9J -----END PGP SIGNATURE----- Merge tag 'imx-drm-fixes-2019-07-04' of git://git.pengutronix.de/git/pza/linux into drm-fixes drm/imx: fix stale vblank timestamp after a modeset This series fixes stale vblank timestamps in the first event sent after a crtc was disabled.
