[PATCH v3 0/2] drm: rework flip-work framework

[Boris BREZILLON]

Hello,

This patch series reworks the flip-work framework to make it safe when
calling drm_flip_work_queue from atomic contexts.

The 2nd patch of this series is optional, as it only reworks
drm_flip_work_init prototype to remove unneeded size argument and
return code (this function cannot fail anymore).

Best Regards,

Boris

Changes since v2:
- add missing spin_lock_init
- fix flip utils description

Changes since v1:
- add gfp flags argument to drm_flip_work_allocate_task function
- make drm_flip_work_queue safe when called from atomic context

    full
