One needs to ensure that the crtcs are shutdown so that the drm_crtc_state->connector_mask reflects that no connectors are currently active. Further, it reduces the reference count for each connector. This ensures that the connectors and encoders can be cleanly removed either when _unbind is called for the corresponding drivers or by drm_mode_config_cleanup(). We need drm_atomic_helper_shutdown() to be called before component_unbind_all() otherwise the connectors attached to the component device will have the wrong reference count value and will not be cleanly removed.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
