mainlining shenanigans
eca22edb37
The current atomic helpers have either their object state being passed as
an argument or the full atomic state.
The former is the pattern that was done at first, before switching to the
latter for new hooks or when it was needed.
Now that the CRTCs have been converted, let's move forward with the
connectors to provide a consistent interface.
The conversion was done using the coccinelle script below, and built tested
on all the drivers.

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.
