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

Hello Dave,

I'm resending this series because I haven't had any news despite for a
while.

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


Boris Brezillon (2):
  drm: rework flip-work helpers to avoid calling func when the FIFO is
    full
  drm: flip-work: change drm_flip_work_init prototype
