[Intel-gfx] [PATCH 0/3] drm/i915: A few more vblank interrupt fixes

[ville.syrjala at linux.intel.com]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

We have a few more corner cases with the drm_vblank_on/off stuff. This
series aims to fix those.

I couldn't think of a good way to write a test case for the drm_vblank_get()
issue since it's a transient state that occurs briefly during modeset. So
I added asserts for it instead.

So far I didn't write a test for the intel_sanitize_crtc() case either. But
I can try to think of something for that...

Ville Syrjälä (3):
  drm: Always reject drm_vblank_get() after drm_vblank_off()
  drm/i915: Warn if drm_vblank_get() still works after drm_vblank_off()
  drm/i915: Re-enable vblank irqs for already active pipes
