The way any singular display pipeline, in need of a modeset, gets enabled is as follows - crtc enable (all) bridge pre-enable encoder enable (all) bridge enable - and the disable sequence is exactly the reverse of this. The crtc operations occur by looping over the old and new crtc states, while the encoder and bridge operations occur together, by looping over the connector states of the display pipelines. Refactor these operations - crtc enable/disable, and encoder & bridge (pre/post) enable/disable - into separate functions each, to make way for the re-ordering of the enable/disable sequences. This patch doesn't alter the sequence of crtc/encoder/bridge operations in any way, but helps to cleanly pave the way for the next two patches, by maintaining logical bisectability.

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 reStructuredText 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.
