[PATCH 0/8] drm/i915: Stop using get_existing_state.

drm_atomic_get_existing_state should be removed, so stop using it in i915.
Fortunately all places can be converted to use the new state or old state,
even removing some dereferncing of obj->state in the process.

i915 no longer depends on plane->fb, so patch 6 removes the assignment.

The first 6 patches should definitely be upstreamed, last 2 are RFC,
but probably should be upstreamed. I added them because I'm curious if
it fixes FD.org #101597.

Maarten Lankhorst (8):
drm/i915: Change use get_new_plane_state instead of existing plane
state
drm/i915: Change get_existing_crtc_state to old state
drm/i915: Use new atomic helpers in intel_plane_atomic_check
drm/i915: Use intel_atomic_get_new_crtc_state in intel_fbc.c
drm/i915: Remove last references to drm_atomic_get_existing* macros
drm/i915: Do not update legacy state any more
drm/i915: Calculate ironlake intermediate watermarks correctly, v2.
drm/i915: Calculate vlv/chv intermediate watermarks correctly, v3.
