Subject: [PATCH v3 2/2] drm: flip-work: change drm_flip_work_init prototype
Now that we're using lists instead of kfifo to store drm flip-work tasks
we do not need the size parameter passed to drm_flip_work_init function
anymore.
Moreover this function cannot fail anymore, we can thus remove the return
code.
Modify drm_flip_work_init users to take account of these changes.
