Hi Imre,
Works fine. But we should wait for Rob's patch set to be merged to -next, and this may be rebased on top of latest Rob's patch set again.
Thanks,

The patchset adds the missing event_lock when accessing the
vblank_event_list in drm_vblank_off() and as preparation for this
also fixes a few other issues in the exynos driver.
This is also a dependency for Rob Clark's drm_send_vblank_event()
rework as that would trigger a warning for the unhold event_lock without
this changeset.
The exynos changes are only compile tested, the rest is tested on an
Intel IVB machine on top of drm-intel-nightly + drm_send_vblank_event()
rework, with i-g-t/flip_test.

In v2:
- Instead of fixing the event_lock vs. vblank_time_lock lockdep issue in
drm_handle_vblank(), fix it in the exynos driver. This looks like the
more logical thing to do and this way we also have a smaller impact on
the rest of DRM code.
Imre Deak (4):
drm/exynos: hold event_lock while accessing pageflip_event_list
drm/exynos: call drm_vblank_put for each queued flip event
drm/exynos: fix lockdep for event_lock wrt. vbl_time_lock
drm: hold event_lock while accessing vblank_event_list
