[PATCH 00/39] drm/atomic: Get rid of existing states (not really)

[Maxime Ripard]

Hi,

Here's a series to get rid of the drm_atomic_helper_get_existing_*_state
accessors.

The initial intent was to remove the __drm_*_state->state pointer to
only rely on old and new states, but we still need it now to know which
of the two we need to free: if a state has not been committed (either
dropped or checked only), then we need to free the new one, if it has
been committed we need to free the old state. 

Thus, the state pointer is kept (and documented) only to point to the
state we should free eventually.

All users have been converted to the relevant old or new state
accessors.  

This was build tested only.

Let me know what you think,
Maxime
