c129b49825Only planes' prepare_fb and cleanup_fb, and encoders' atomic_check and atomic_mode_set hooks remain with an object state and not the global drm_atomic_state. prepare_fb and cleanup_fb operate by design on a given state and depending on the calling site can operate on either the old or new state, so it doesn't really make much sense to convert them. The encoders' atomic_check and atomic_mode_set operate on the CRTC and connector state connected to them since encoders don't have a state of their own. Without those state pointers, we would need to get the CRTC through the drm_connector_state crtc pointer. However, in order to get the drm_connector_state pointer, we would need to get the connector itself and while usually we have a single connector connected to the encoder, we can't really get it from the encoder at the moment since it could be behind any number of bridges. While this could be addressed by (for example) listing all the connectors and finding the one that has the encoder as its source, it feels like an unnecessary rework for something that is slowly getting replaced by bridges. Since all the users that matter have been converted, let's remove the TODO item.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
