The uapi vs. hw state split introduced a bug in
intel_crtc_disable_noatomic() where it's now frobbing an already
freed temp crtc state instead of adjusting the crtc state we
are really left with. Fix that by making a cleaner separation
beteen the two.
This causes explosions on any machine that boots up with pipes
already running but not hooked up to any encoder (typical
behaviour for gen2-4 VBIOS).

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.
