It'll land (presuming nothing really terrible shows up) in 3.13.

[PATCH v2] drm/exynos: release unhandled page flip events at postclose.
by Inki Dae 01 Oct '13

01 Oct '13

This patch resolves a dead lock issue that could be incurred when exynos_drm_crtc_dpms function was called. The exynos_drm_crtc_dpms function waits for the completion of pended page flip events. However, preclose callback - this releases all unhandled page flip events - is called prior to the exynos_drm_crtc_dpms function call when drm is closed. So at this time, this will make the exynos_drm_crtc_dpms to wait infiniately for the completion of the page flip events. This patch releases the unhandled page flip events at postclose instead of preclose so that exynos_drm_crtc_dpms function can be waked up. Changelog v2: - fix a memory leak when drm is closed. . it has a memory leak when a requeste page flip is handled after drm_events_release() is called and before drm_fb_release() is called. At this time, a drm_pending_event will not be freed. So also this chage releases the drm_pending_event at postclose(). And it calls drm_vblank_put() for pair if there is any unhandled page flip event.
