| Subject: [PATCH 249/286] drm: rcar-du: Handle event when disabling CRTCs |
| |
| The driver currently handles vblank events only when updating planes on |
| a CRTC. The atomic update API however allows requesting an event when |
| disabling a CRTC. This currently leads to event objects being leaked in |
| the kernel and to events not being sent out. Fix it. |
